Oscar fish, often called velvet cichlids, are a big hit in the world of home aquariums. They look stunning, and their quirky behaviors are a joy to watch.<\/p>\n
However, there are some things you need to know about Oscar fish care if you plan on owning one.<\/p>\n
You see, these fish are quite aggressive and can quickly cause problems if you intend on keeping them with other fish. That\u2019s why we always recommend that you have some experience as an aquarist before owning one.<\/p>\n
But don\u2019t let us discourage you! Oscars can be incredibly rewarding aquarium fish to care for, and once you know what you\u2019re doing it\u2019s rather straightforward.<\/p>\n
That\u2019s why we wanted to put together this care guide. In it, you\u2019ll learn everything you need to know about Oscar fish care and helpful facts about the species.<\/p>\n
Species Summary<\/strong><\/h2>\nOscar fish come from South America, namely Peru, Brazil, French Guiana, Colombia, and Ecuador. Their scientific name is Astronotus ocellatus (if you\u2019re curious about that sort of thing). <\/em>Large numbers of these fish can be found in the Amazon River basin, and prefer slow-moving water with lots of rocks and debris.<\/p>\nAlthough they are naturally from this area, you can also find them in Australia, China, and even Florida. Oscars that are found here have either escaped during fish trade transit or dumped by owners who could not take care of them.<\/p>\n
They are known for their stunning looks, unique personality, and aggression.<\/p>\n
Oscar Fish Lifespan<\/strong><\/h3>\nThe average Oscar fish lifespan is somewhere between 10 and 13 years. However, an Oscar with great genetics and good care can live to be over 15 years old!<\/p>\n
Their lifespan is often overlooked by potential owners, and once they learn this they are often blown away. When you compare this to other related fish like the African cichlid<\/a> there\u2019s a big difference in age.<\/p>\nIn our opinion, this is one of the biggest benefits of getting an Oscar fish. We love the idea of owning and caring for them over a long period of time.<\/p>\n
In our experience, the bond and attachment you build when having a fish for that long really makes the experience that much more rewarding!<\/p>\n
Appearance<\/strong><\/h2>\nThe appearance of Oscar fish can vary between the types, but all of them look fantastic. The beauty of this tropical fish is something that can\u2019t be said enough!<\/p>\n
\n![\"Oscar](\"https:\/\/www.aquariumsource.com\/wp-content\/uploads\/2019\/10\/oscar-fish-care-1024x682.jpg\")
<\/figure>\n<\/div>\nThe general body type of these fish is rather long and egg-shaped. Just like many other cichlids, their caudal fins are pretty symmetrical and standard, not sticking out too far.<\/p>\n
Their dorsal fins run all the way down to their caudal fins, giving them a sort of beefy look. The same thing goes for their anal fins as well. This makes them look kind of like chunky torpedoes in the water.<\/p>\n
Their eyes are large and are typically surrounded by an uncolored patch on their bodies that extends up to the start of their dorsal fin.<\/p>\n
Types Of Oscar Fish<\/strong><\/h2>\nBelow we list the different kinds of Oscar fish and what they look like.<\/p>\n
Tiger Oscar Fish<\/strong><\/h3>\nThis is the classic color pattern that you see with most Oscars. As you can probably tell by the name, tiger Oscar fish are black and orange.<\/p>\n
Unlike tigers, they don\u2019t have orange stripes (or is that black stripes?) and instead have a more sporadic pattern. They have a black body with orange lines and blotches that extend in random directions.<\/p>\n
It kind of looks like a mix between a Rorschach test and a maze. Their body is usually free of color from their upper lip to the start of their dorsal fin.<\/p>\n
Red Oscar Fish<\/strong><\/h3>\nRed Oscar fish are pretty much exactly that, red. The red coloring is mostly on their sides and unlike the tiger variation, is hardly patterned. They are mostly solid red on the side with no color on any of their fins.<\/p>\n
Albino Oscar Fish<\/strong><\/h3>\nLike many other species in the aquarist community, albino Oscar fish are highly sought after due to their unique look. With albino Oscars, the red coloring on the side is typically more scattered than the orange on the Tigers. It\u2019s also more of a \u201clarge shape made of dots\u201d kind of design as well.<\/p>\n
\n![\"Albino](\"https:\/\/www.aquariumsource.com\/wp-content\/uploads\/2019\/10\/albino-oscar-fish-1024x768.jpg\")
<\/figure>\n<\/div>\nAs you probably guessed, the main body color of albino Oscar fish is white. We\u2019ve had the opportunity to see a few of these over the years and they definitely steal the show when you\u2019re observing a tank!<\/p>\n
Black Oscar Fish<\/strong><\/h3>\nBlack Oscar fish are another neat type that is on the rise lately. They have a very similar side pattern to the Albino but instead, the colors are 100% stealth.<\/p>\n
Black and grey are the dominant colors and it gives them a unique look especially when compared to the louder alternatives that other types offer.<\/p>\n
Lemon Oscar Fish<\/strong><\/h3>\nThe Lemon Oscar fish is basically the same thing as the red Oscar, just yellow. The color patterns on their sides follow the same kind of rhythm, it\u2019s just done with different colors.<\/p>\n
Size<\/strong><\/h2>\nThe average Oscar fish size is somewhere between 10 and 12 inches long<\/strong> when in captivity. When in their natural habitat this fish can exceed the 14-15 inch mark.<\/p>\nDue to their large size, you need to make sure Oscars have the proper space to thrive and live a comfortable, low-stress life. We cover tank size in the following section.<\/p>\n
Oscar Fish Care<\/strong><\/h2>\nIf you want to provide good Oscar fish care, there are a handful of things you\u2019ll need to do. While a large part of keeping this fish happy revolves around managing their temperament, you need to get the basics right first.<\/p>\n
Although these fish are hardy, you never want to rely on that. Providing them with the best possible living environment should always be the goal.<\/p>\n
Tank Size<\/strong><\/h3>\nThe ideal Oscar fish tank size should be at least 55 gallons. These are large fish, so they need a large tank that can accommodate them.<\/p>\n
If you\u2019re planning on owning multiple Oscar fish, then you\u2019ll need to ramp up the tank size. Plan to add at least 25 additional gallons of water for each new Oscar you add.<\/p>\n
This means for one fish you\u2019ll want (at minimum) a 55 gallon tank, 80 gallons for two, 105 gallons for three, and so on.<\/p>\n
Ensuring you have the proper tank size should always be step one for trying to provide great care for your Oscar fish. After all, this is the home that they\u2019ll be living in!<\/p>\n
If they don\u2019t have enough room to be comfortable their health will suffer due to stress. Not only that, but the aggressive nature<\/a> of this fish can be amplified when confined to a small space (not fun for anyone involved).<\/p>\nWater Parameters<\/strong><\/h3>\nNext, you want to make sure that your water parameters are within the recommended guidelines. This will make a massive impact on the lifespan of your Oscar fish and will ensure their health over time.<\/p>\n
\n- Water temperature<\/strong>: 75-80\u00b0F<\/li>\n
- pH levels<\/strong>: Between 6 and 8<\/li>\n
- Water hardness<\/strong>: 12-15dH<\/li>\n<\/ul>\n
You won\u2019t need to worry about fancy filtration or lighting, which makes Oscar fish care a little easier. A standard filter and light will do just fine. You don\u2019t even need to worry about air or water pumps to produce the necessary amount of current.<\/p>\n
Lastly, make sure you\u2019re consistent about doing water level tests. Significant water changes can lead to serious health issues for your Oscars.<\/p>\n
What To Put In Their Tank<\/strong><\/h3>\nHaving a good tank setup is extremely important as well. Plenty of inexperienced aquarists think that all you need to worry about is water quality parameters, and putting a lot of effort into what goes inside the tank is a waste of time.<\/p>\n
We can\u2019t express just how wrong this is.<\/p>\n
The way you set up your Oscars tank will significantly impact their enrichment and stress levels over time. If you want them to be happy and healthy, pay close attention to this section!<\/p>\n
\n- Hiding places<\/strong>: It\u2019s important to give your Oscar fish a place to hide so they can feel comfortable and safe. Rocks and driftwood are great options. Oscars aren\u2019t picky though, so anything that will serve as a suitable hiding spot is fine with them.<\/li>\n
- Plants<\/strong>: If you want to add plants to their tank it\u2019s usually smart to go with a plant that can float like Hornwort<\/a>. They won\u2019t be damaged by any of the digging Oscars do and will grow like a weed no matter what you throw at them.<\/li>\n
- Substrate<\/strong>: You\u2019ll want to make sure there\u2019s a soft substrate on the bottom of the tank. Oscars like to root around and churn through the substrate on occasion, and you don\u2019t want them to get cut while doing this.<\/li>\n<\/ul>\n
Hole In The Head Disease<\/strong><\/h3>\nThere\u2019s one disease that you\u2019ll want to keep an eye out for with Oscar fish in particular. It\u2019s called Hole in the Head disease and it is definitely not something you want your fish to get.<\/p>\n
The symptoms are one or two small holes in the head of your Oscar. These will get worse over time if left untreated, and will likely cause scarring after they have recovered.<\/p>\n
As gruesome as this sounds, Hole in the Head disease is something you can cure and also prevent. Maintaining great water quality within the recommended parameters will pretty much guarantee that your fish won\u2019t get this disease.<\/p>\n
If you see that your fish is developing this disease then it\u2019s time for you to get to work. You\u2019ll need to do water tests and likely change the water in the tank of you find that there are issues. This guide<\/a> is a great resource that goes into each step of the process.<\/p>\nFood & Diet<\/strong><\/h2>\nWhen it comes to the best Oscar fish food, you have a number of options to choose from. This is because Oscars are not picky when it comes to what they eat (they\u2019re omnivores)<\/p>\n
In their natural habitats, Oscars typically eat insects, the occasional fish, and will nibble on whatever plants that strike their fancy.<\/p>\n
In your freshwater aquarium, you\u2019ll likely be feeding them a mix of processed and live food. Pretty much any cichlid-friendly pellets or flakes are just fine. For live food, two of the most common solutions are brine shrimp and bloodworms<\/a>. You can even feed them live crickets and grasshoppers.<\/p>\nIf you want to experiment with some additional foods to supplement the diet of your Oscar fish, there are a few other options. Some aquarists have experimented with occasionally feeding their Oscars nuts or fruits, but this is something you\u2019ll want to limit quite heavily.<\/p>\n
Frozen peas have also been reported to provide a nice boost in energy and the richness of color in your fish (they also seem to love them). Again, this is Oscar fish food that you\u2019ll want to reserve as a special treat.<\/p>\n
Behavior & Temperament<\/strong><\/h2>\nOscar fish behavior is something that can be misunderstood. When people hear that this fish is aggressive, they sometimes think that they are downright mean.<\/p>\n
That\u2019s not the case.<\/p>\n
Yes, Oscars have the potential to be quite aggressive and territorial. However, this will typically only show if you have them in a suboptimal tank environment.<\/p>\n
\n![\"Tiger](\"https:\/\/www.aquariumsource.com\/wp-content\/uploads\/2019\/10\/tiger-oscar-fish-1024x683.jpg\")
<\/figure>\n<\/div>\nBeing too crowded or pairing them with tank mates that aren\u2019t a good fit is a recipe for disaster. But if you\u2019ve done your homework and have them in an environment where they feel comfortable, your Oscars can actually be pretty mellow!<\/p>\n
Aside from their aggression, there\u2019s one Oscar fish behavior that\u2019s worth noting before we move on (we hinted at it above). These fish love to scrounge through your substrate in an attempt to dig up some food.<\/p>\n
This means you need to be prepared for them to occupy the middle (where they spend most of their time) and bottom of the tank throughout the day.<\/p>\n
Oscar Fish Tank Mates<\/strong><\/h2>\nWith their potential for aggression, finding the best tank mates for Oscar fish is obviously a priority for many new owners.<\/p>\n
If you want to play it safe the best tank mates for Oscar fish, are other Oscar fish. This is a pretty common rule when it comes to aggressive species of fish.<\/p>\n
All you need to do in this case if make sure you follow the minimum tank size protocols and you should be good to go!<\/p>\n
Community Tank Mates<\/strong><\/h3>\nIf you want to keep your Oscars with tank mates of another species you\u2019ll have to be a little more careful.<\/p>\n
Due to their aggression, the confined nature of a freshwater aquarium makes it difficult to fully guarantee there won\u2019t be conflict (even if your tank size is large enough).\u00a0<\/p>\n
This means you\u2019re going to have to look for fish that are large enough to hold their own but won\u2019t feel the need to pick a fight.<\/p>\n
Small fish like goldfish or guppies<\/a> will be toast if kept in a tank with Oscars. If you\u2019re using them as feeder fish that\u2019s a whole other story of course.<\/p>\nSome good Oscar fish tank mates include:<\/p>\n
Although they are naturally from this area, you can also find them in Australia, China, and even Florida. Oscars that are found here have either escaped during fish trade transit or dumped by owners who could not take care of them.<\/p>\n
They are known for their stunning looks, unique personality, and aggression.<\/p>\n
Oscar Fish Lifespan<\/strong><\/h3>\nThe average Oscar fish lifespan is somewhere between 10 and 13 years. However, an Oscar with great genetics and good care can live to be over 15 years old!<\/p>\n
Their lifespan is often overlooked by potential owners, and once they learn this they are often blown away.

This means for one fish you\u2019ll want (at minimum) a 55 gallon tank, 80 gallons for two, 105 gallons for three, and so on.<\/p>\n
Ensuring you have the proper tank size should always be step one for trying to provide great care for your Oscar fish. After all, this is the home that they\u2019ll be living in!<\/p>\n
If they don\u2019t have enough room to be comfortable their health will suffer due to stress. Not only that, but the aggressive nature<\/a> of this fish can be amplified when confined to a small space (not fun for anyone involved).<\/p>\nWater Parameters<\/strong><\/h3>\nNext, you want to make sure that your water parameters are within the recommended guidelines. This will make a massive impact on the lifespan of your Oscar fish and will ensure their health over time.<\/p>\n
\n- Water temperature<\/strong>: 75-80\u00b0F<\/li>\n
- pH levels<\/strong>: Between 6 and 8<\/li>\n
- Water hardness<\/strong>: 12-15dH<\/li>\n<\/ul>\n
You won\u2019t need to worry about fancy filtration or lighting, which makes Oscar fish care a little easier. A standard filter and light will do just fine. You don\u2019t even need to worry about air or water pumps to produce the necessary amount of current.<\/p>\n
Lastly, make sure you\u2019re consistent about doing water level tests. Significant water changes can lead to serious health issues for your Oscars.<\/p>\n
What To Put In Their Tank<\/strong><\/h3>\nHaving a good tank setup is extremely important as well. Plenty of inexperienced aquarists think that all you need to worry about is water quality parameters, and putting a lot of effort into what goes inside the tank is a waste of time.<\/p>\n
We can\u2019t express just how wrong this is.<\/p>\n
The way you set up your Oscars tank will significantly impact their enrichment and stress levels over time. If you want them to be happy and healthy, pay close attention to this section!<\/p>\n
\n- Hiding places<\/strong>: It\u2019s important to give your Oscar fish a place to hide so they can feel comfortable and safe. Rocks and driftwood are great options. Oscars aren\u2019t picky though, so anything that will serve as a suitable hiding spot is fine with them.<\/li>\n
- Plants<\/strong>: If you want to add plants to their tank it\u2019s usually smart to go with a plant that can float like Hornwort<\/a>. They won\u2019t be damaged by any of the digging Oscars do and will grow like a weed no matter what you throw at them.<\/li>\n
- Substrate<\/strong>: You\u2019ll want to make sure there\u2019s a soft substrate on the bottom of the tank. Oscars like to root around and churn through the substrate on occasion, and you don\u2019t want them to get cut while doing this.<\/li>\n<\/ul>\n
Hole In The Head Disease<\/strong><\/h3>\nThere\u2019s one disease that you\u2019ll want to keep an eye out for with Oscar fish in particular. It\u2019s called Hole in the Head disease and it is definitely not something you want your fish to get.<\/p>\n
The symptoms are one or two small holes in the head of your Oscar. These will get worse over time if left untreated, and will likely cause scarring after they have recovered.<\/p>\n
As gruesome as this sounds, Hole in the Head disease is something you can cure and also prevent. Maintaining great water quality within the recommended parameters will pretty much guarantee that your fish won\u2019t get this disease.<\/p>\n
If you see that your fish is developing this disease then it\u2019s time for you to get to work. You\u2019ll need to do water tests and likely change the water in the tank of you find that there are issues. This guide<\/a> is a great resource that goes into each step of the process.<\/p>\nFood & Diet<\/strong><\/h2>\nWhen it comes to the best Oscar fish food, you have a number of options to choose from. This is because Oscars are not picky when it comes to what they eat (they\u2019re omnivores)<\/p>\n
In their natural habitats, Oscars typically eat insects, the occasional fish, and will nibble on whatever plants that strike their fancy.<\/p>\n
In your freshwater aquarium, you\u2019ll likely be feeding them a mix of processed and live food. Pretty much any cichlid-friendly pellets or flakes are just fine. For live food, two of the most common solutions are brine shrimp and bloodworms<\/a>. You can even feed them live crickets and grasshoppers.<\/p>\nIf you want to experiment with some additional foods to supplement the diet of your Oscar fish, there are a few other options. Some aquarists have experimented with occasionally feeding their Oscars nuts or fruits, but this is something you\u2019ll want to limit quite heavily.<\/p>\n
Frozen peas have also been reported to provide a nice boost in energy and the richness of color in your fish (they also seem to love them). Again, this is Oscar fish food that you\u2019ll want to reserve as a special treat.<\/p>\n
Behavior & Temperament<\/strong><\/h2>\nOscar fish behavior is something that can be misunderstood. When people hear that this fish is aggressive, they sometimes think that they are downright mean.<\/p>\n
That\u2019s not the case.<\/p>\n
Yes, Oscars have the potential to be quite aggressive and territorial. However, this will typically only show if you have them in a suboptimal tank environment.<\/p>\n
\n<\/figure>\n<\/div>\nBeing too crowded or pairing them with tank mates that aren\u2019t a good fit is a recipe for disaster. But if you\u2019ve done your homework and have them in an environment where they feel comfortable, your Oscars can actually be pretty mellow!<\/p>\n
Aside from their aggression, there\u2019s one Oscar fish behavior that\u2019s worth noting before we move on (we hinted at it above). These fish love to scrounge through your substrate in an attempt to dig up some food.<\/p>\n
This means you need to be prepared for them to occupy the middle (where they spend most of their time) and bottom of the tank throughout the day.<\/p>\n
Oscar Fish Tank Mates<\/strong><\/h2>\nWith their potential for aggression, finding the best tank mates for Oscar fish is obviously a priority for many new owners.<\/p>\n
If you want to play it safe the best tank mates for Oscar fish, are other Oscar fish. This is a pretty common rule when it comes to aggressive species of fish.<\/p>\n
All you need to do in this case if make sure you follow the minimum tank size protocols and you should be good to go!<\/p>\n
Community Tank Mates<\/strong><\/h3>\nIf you want to keep your Oscars with tank mates of another species you\u2019ll have to be a little more careful.<\/p>\n
Due to their aggression, the confined nature of a freshwater aquarium makes it difficult to fully guarantee there won\u2019t be conflict (even if your tank size is large enough).\u00a0<\/p>\n
This means you\u2019re going to have to look for fish that are large enough to hold their own but won\u2019t feel the need to pick a fight.<\/p>\n
Small fish like goldfish or guppies<\/a> will be toast if kept in a tank with Oscars. If you\u2019re using them as feeder fish that\u2019s a whole other story of course.<\/p>\nSome good Oscar fish tank mates include:<\/p>\n
<\/figure>\n<\/div>\nThe general body type of these fish is rather long and egg-shaped. Just like many other cichlids, their caudal fins are pretty symmetrical and standard, not sticking out too far.<\/p>\n
Their dorsal fins run all the way down to their caudal fins, giving them a sort of beefy look. The same thing goes for their anal fins as well. This makes them look kind of like chunky torpedoes in the water.<\/p>\n
Their eyes are large and are typically surrounded by an uncolored patch on their bodies that extends up to the start of their dorsal fin.<\/p>\n
Types Of Oscar Fish<\/strong><\/h2>\nBelow we list the different kinds of Oscar fish and what they look like.<\/p>\n
Tiger Oscar Fish<\/strong><\/h3>\nThis is the classic color pattern that you see with most Oscars. As you can probably tell by the name, tiger Oscar fish are black and orange.<\/p>\n
Unlike tigers, they don\u2019t have orange stripes (or is that black stripes?) and instead have a more sporadic pattern. They have a black body with orange lines and blotches that extend in random directions.<\/p>\n
It kind of looks like a mix between a Rorschach test and a maze. Their body is usually free of color from their upper lip to the start of their dorsal fin.<\/p>\n
Red Oscar Fish<\/strong><\/h3>\nRed Oscar fish are pretty much exactly that, red. The red coloring is mostly on their sides and unlike the tiger variation, is hardly patterned. They are mostly solid red on the side with no color on any of their fins.<\/p>\n
Albino Oscar Fish<\/strong><\/h3>\nLike many other species in the aquarist community, albino Oscar fish are highly sought after due to their unique look. With albino Oscars, the red coloring on the side is typically more scattered than the orange on the Tigers. It\u2019s also more of a \u201clarge shape made of dots\u201d kind of design as well.<\/p>\n
\n<\/figure>\n<\/div>\nAs you probably guessed, the main body color of albino Oscar fish is white. We\u2019ve had the opportunity to see a few of these over the years and they definitely steal the show when you\u2019re observing a tank!<\/p>\n
Black Oscar Fish<\/strong><\/h3>\nBlack Oscar fish are another neat type that is on the rise lately. They have a very similar side pattern to the Albino but instead, the colors are 100% stealth.<\/p>\n
Black and grey are the dominant colors and it gives them a unique look especially when compared to the louder alternatives that other types offer.<\/p>\n
Lemon Oscar Fish<\/strong><\/h3>\nThe Lemon Oscar fish is basically the same thing as the red Oscar, just yellow. The color patterns on their sides follow the same kind of rhythm, it\u2019s just done with different colors.<\/p>\n
Size<\/strong><\/h2>\nThe average Oscar fish size is somewhere between 10 and 12 inches long<\/strong> when in captivity. When in their natural habitat this fish can exceed the 14-15 inch mark.<\/p>\nDue to their large size, you need to make sure Oscars have the proper space to thrive and live a comfortable, low-stress life. We cover tank size in the following section.<\/p>\n
Oscar Fish Care<\/strong><\/h2>\nIf you want to provide good Oscar fish care, there are a handful of things you\u2019ll need to do. While a large part of keeping this fish happy revolves around managing their temperament, you need to get the basics right first.<\/p>\n
Although these fish are hardy, you never want to rely on that. Providing them with the best possible living environment should always be the goal.<\/p>\n
Tank Size<\/strong><\/h3>\nThe ideal Oscar fish tank size should be at least 55 gallons. These are large fish, so they need a large tank that can accommodate them.<\/p>\n
If you\u2019re planning on owning multiple Oscar fish, then you\u2019ll need to ramp up the tank size. Plan to add at least 25 additional gallons of water for each new Oscar you add.<\/p>\n

Oscar Fish Care<\/strong><\/h2>\nIf you want to provide good Oscar fish care, there are a handful of things you\u2019ll need to do. While a large part of keeping this fish happy revolves around managing their temperament, you need to get the basics right first.<\/p>\n
Although these fish are hardy, you never want to rely on that. Providing them with the best possible living environment should always be the goal.<\/p>\n
Tank Size<\/strong><\/h3>\nThe ideal Oscar fish tank size should be at least 55 gallons. These are large fish, so they need a large tank that can accommodate them.<\/p>\n
If you\u2019re planning on owning multiple Oscar fish, then you\u2019ll need to ramp up the tank size. Plan to add at least 25 additional gallons of water for each new Oscar you add.<\/p>\n
This means for one fish you\u2019ll want (at minimum) a 55 gallon tank, 80 gallons for two, 105 gallons for three, and so on.<\/p>\n
Ensuring you have the proper tank size should always be step one for trying to provide great care for your Oscar fish. After all, this is the home that they\u2019ll be living in!<\/p>\n
If they don\u2019t have enough room to be comfortable their health will suffer due to stress. Not only that, but the aggressive nature<\/a> of this fish can be amplified when confined to a small space (not fun for anyone involved).<\/p>\nWater Parameters<\/strong><\/h3>\nNext, you want to make sure that your water parameters are within the recommended guidelines. This will make a massive impact on the lifespan of your Oscar fish and will ensure their health over time.<\/p>\n
\n- Water temperature<\/strong>: 75-80\u00b0F<\/li>\n
- pH levels<\/strong>: Between 6 and 8<\/li>\n
- Water hardness<\/strong>: 12-15dH<\/li>\n<\/ul>\n
You won\u2019t need to worry about fancy filtration or lighting, which makes Oscar fish care a little easier. A standard filter and light will do just fine. You don\u2019t even need to worry about air or water pumps to produce the necessary amount of current.<\/p>\n
Lastly, make sure you\u2019re consistent about doing water level tests. Significant water changes can lead to serious health issues for your Oscars.<\/p>\n
What To Put In Their Tank<\/strong><\/h3>\nHaving a good tank setup is extremely important as well. Plenty of inexperienced aquarists think that all you need to worry about is water quality parameters, and putting a lot of effort into what goes inside the tank is a waste of time.<\/p>\n
We can\u2019t express just how wrong this is.<\/p>\n
The way you set up your Oscars tank will significantly impact their enrichment and stress levels over time. If you want them to be happy and healthy, pay close attention to this section!<\/p>\n
\n- Hiding places<\/strong>: It\u2019s important to give your Oscar fish a place to hide so they can feel comfortable and safe. Rocks and driftwood are great options. Oscars aren\u2019t picky though, so anything that will serve as a suitable hiding spot is fine with them.<\/li>\n
- Plants<\/strong>: If you want to add plants to their tank it\u2019s usually smart to go with a plant that can float like Hornwort<\/a>. They won\u2019t be damaged by any of the digging Oscars do and will grow like a weed no matter what you throw at them.<\/li>\n
- Substrate<\/strong>: You\u2019ll want to make sure there\u2019s a soft substrate on the bottom of the tank. Oscars like to root around and churn through the substrate on occasion, and you don\u2019t want them to get cut while doing this.<\/li>\n<\/ul>\n
Hole In The Head Disease<\/strong><\/h3>\nThere\u2019s one disease that you\u2019ll want to keep an eye out for with Oscar fish in particular. It\u2019s called Hole in the Head disease and it is definitely not something you want your fish to get.<\/p>\n
The symptoms are one or two small holes in the head of your Oscar. These will get worse over time if left untreated, and will likely cause scarring after they have recovered.<\/p>\n
As gruesome as this sounds, Hole in the Head disease is something you can cure and also prevent. Maintaining great water quality within the recommended parameters will pretty much guarantee that your fish won\u2019t get this disease.<\/p>\n
If you see that your fish is developing this disease then it\u2019s time for you to get to work. You\u2019ll need to do water tests and likely change the water in the tank of you find that there are issues. This guide<\/a> is a great resource that goes into each step of the process.<\/p>\nFood & Diet<\/strong><\/h2>\nWhen it comes to the best Oscar fish food, you have a number of options to choose from. This is because Oscars are not picky when it comes to what they eat (they\u2019re omnivores)<\/p>\n
In their natural habitats, Oscars typically eat insects, the occasional fish, and will nibble on whatever plants that strike their fancy.<\/p>\n
In your freshwater aquarium, you\u2019ll likely be feeding them a mix of processed and live food. Pretty much any cichlid-friendly pellets or flakes are just fine. For live food, two of the most common solutions are brine shrimp and bloodworms<\/a>. You can even feed them live crickets and grasshoppers.<\/p>\nIf you want to experiment with some additional foods to supplement the diet of your Oscar fish, there are a few other options. Some aquarists have experimented with occasionally feeding their Oscars nuts or fruits, but this is something you\u2019ll want to limit quite heavily.<\/p>\n
Frozen peas have also been reported to provide a nice boost in energy and the richness of color in your fish (they also seem to love them). Again, this is Oscar fish food that you\u2019ll want to reserve as a special treat.<\/p>\n
Behavior & Temperament<\/strong><\/h2>\nOscar fish behavior is something that can be misunderstood. When people hear that this fish is aggressive, they sometimes think that they are downright mean.<\/p>\n
That\u2019s not the case.<\/p>\n
Yes, Oscars have the potential to be quite aggressive and territorial. However, this will typically only show if you have them in a suboptimal tank environment.<\/p>\n
\n<\/figure>\n<\/div>\nBeing too crowded or pairing them with tank mates that aren\u2019t a good fit is a recipe for disaster. But if you\u2019ve done your homework and have them in an environment where they feel comfortable, your Oscars can actually be pretty mellow!<\/p>\n
Aside from their aggression, there\u2019s one Oscar fish behavior that\u2019s worth noting before we move on (we hinted at it above). These fish love to scrounge through your substrate in an attempt to dig up some food.<\/p>\n
This means you need to be prepared for them to occupy the middle (where they spend most of their time) and bottom of the tank throughout the day.<\/p>\n
Oscar Fish Tank Mates<\/strong><\/h2>\nWith their potential for aggression, finding the best tank mates for Oscar fish is obviously a priority for many new owners.<\/p>\n
If you want to play it safe the best tank mates for Oscar fish, are other Oscar fish. This is a pretty common rule when it comes to aggressive species of fish.<\/p>\n
All you need to do in this case if make sure you follow the minimum tank size protocols and you should be good to go!<\/p>\n
Community Tank Mates<\/strong><\/h3>\nIf you want to keep your Oscars with tank mates of another species you\u2019ll have to be a little more careful.<\/p>\n
Due to their aggression, the confined nature of a freshwater aquarium makes it difficult to fully guarantee there won\u2019t be conflict (even if your tank size is large enough).\u00a0<\/p>\n
This means you\u2019re going to have to look for fish that are large enough to hold their own but won\u2019t feel the need to pick a fight.<\/p>\n
Small fish like goldfish or guppies<\/a> will be toast if kept in a tank with Oscars. If you\u2019re using them as feeder fish that\u2019s a whole other story of course.<\/p>\nSome good Oscar fish tank mates include:<\/p>\n
The Lemon Oscar fish is basically the same thing as the red Oscar, just yellow. The color patterns on their sides follow the same kind of rhythm, it\u2019s just done with different colors.<\/p>\n
Size<\/strong><\/h2>\nThe average Oscar fish size is somewhere between 10 and 12 inches long<\/strong> when in captivity. When in their natural habitat this fish can exceed the 14-15 inch mark.<\/p>\nDue to their large size, you need to make sure Oscars have the proper space to thrive and live a comfortable, low-stress life. We cover tank size in the following section.<\/p>\n

This is a pretty common rule when it comes to aggressive species of fish.<\/p>\n All you need to do in this case if make sure you follow the minimum tank size protocols and you should be good to go!<\/p>\n If you want to keep your Oscars with tank mates of another species you\u2019ll have to be a little more careful.<\/p>\n Due to their aggression, the confined nature of a freshwater aquarium makes it difficult to fully guarantee there won\u2019t be conflict (even if your tank size is large enough).\u00a0<\/p>\n This means you\u2019re going to have to look for fish that are large enough to hold their own but won\u2019t feel the need to pick a fight.<\/p>\n Small fish like goldfish or guppies<\/a> will be toast if kept in a tank with Oscars. If you\u2019re using them as feeder fish that\u2019s a whole other story of course.<\/p>\n Some good Oscar fish tank mates include:<\/p>\nWater Parameters<\/strong><\/h3>\n
