The Rainbow shark is a well-liked type of freshwater fish. People admire their distinct appearance and similarity to marine sharks.<\/p>\n

However, we think they might be one of the most misunderstood fish, especially by beginners. They can be difficult to keep so it is important to know what they need if you intend to keep this species. This guide will run through everything you need to know about rainbow sharks, including housing, ideal water parameters, feeding, and breeding techniques.<\/p>\n

Rainbow Shark Overview<\/h2>\n

Rainbow Sharks are part of the Cyprinidae family<\/em>. They also go by alternate names such as red-finned or ruby shark. Despite their names, Rainbow sharks are not actual sharks. Ocean sharks belong to the Chondrichtheyes family, but rainbow sharks are part of the Cyprinidae family, which is the same family as minnows. So although they share the shark name, their origins are very different. Instead, they got the cool name because they have a shark-like appearance due to their dorsal fin on top.<\/p>\n

This species is native to Southeast Asia. They thrive in Southeast Asia, particularly the rivers of Myanmar, Thailand, Laos, and Malaysia. They live in rivers with sandy bottoms and lots of plankton. This species was once abundant, but numbers have dwindled in recent years. Most scientists believe the damming of rivers is responsible for the population decline.\u00a0<\/p>\n

Most rainbow sharks available for purchase in aquarium storms originate from fish farms in Thailand so there is little overlap between the wild and captive cohorts.<\/p>\n

Rainbow Shark Appearance<\/h2>\n

The Rainbow Shark<\/a> is a dark gray fish with vibrant reddish orange fins.<\/p>\n

They have a long, torpedo-like body shape, a pointed snout, and an upright dorsal fin. This upright dorsal fin gives them their shark name as it resembles ocean sharks\u2019 fins.<\/p>\n

There is some color variation between males and females. At sexual maturity, males tend to have brighter red or orange fins than females do.<\/p>\n

If you\u2019re looking for a unique variation, you could also get an Albino Rainbow Shark. The Albino Rainbow Shark has the same reddish-orange fins of the regular variety. However, its body is white. Everything else about the Albino Rainbow Shark is the same as the baseline variety.<\/p>\n

How long do Rainbow Sharks live?<\/h2>\n

The average lifespan of a rainbow shark is between four and six years long. There are reports of some fish living up to eight years but that is rare.<\/p>\n

The quality of water in your tank and general tank conditions are key factors in the length of your rainbow shark\u2019s life. Ideal conditions will keep your rainbow shark at low stress levels, which will help it live longer.<\/p>\n

How big do Rainbow Sharks get?<\/h2>\n

The average rainbow shark size at maturity is about 6 inches long. There are some reports of rainbow sharks reaching lengths of 8 inches, but those are rare reports.\u00a0<\/p>\n

Both normal rainbow sharks and albino varieties reach this length. Males and females also tend to be about the same length.<\/p>\n

Rainbow sharks are a fast-growing species. Between two and four weeks of age, the baby fish will have grown to about \u00bd inch to one-inch in length. From there, it can take several months for them to reach full size.<\/p>\n

Rainbow sharks are considered sexually mature when they reach four inches in length.<\/p>\n

Rainbow Shark Temperament<\/h2>\n

Rainbow sharks are territorial fish with aggressive tendencies. For this reason, we don\u2019t recommend other tankmates for rainbow sharks, especially if you\u2019re a beginner.<\/p>\n

If you do go the route of other species tankmates, you must look for species that are also semi-aggressive and similarly sized. Some examples of suitable fish include some gouramis<\/a>, barbs, and danios.<\/p>\n

If you fail to add equally-aggressive and similarly sized fish, the larger and more aggressive fish in the tank are likely to seriously harm, if not kill, the weaker fish. Rainbow sharks like to pick on small fish, such as the Chili Rasbora<\/a>, and bottom-feeders, such as clown plecos<\/a> or cory catfish.<\/p>\n

We also recommend housing at least five rainbow sharks. Your sharks are likely to squabble from time-to-time, so having several ensures that one pair of fish aren\u2019t endlessly fighting. Essentially, the more the merrier within space constraints because it spreads the aggression around.<\/p>\n

Rainbow Shark Care<\/h2>\n

Rainbow sharks do require some sophistication in their care. There are several specifications you\u2019ll want to take into account, around tank size, substrates, filtration, and more.<\/p>\n

Overall, they are hardy fish and don\u2019t need excessive support, but that assumes their essential needs are being met.<\/p>\n

Stick to these guidelines in order to make sure that your rainbow shark lives a healthy life.<\/p>\n

Rainbow Shark Habitat<\/h2>\n

When planning the habitat of your fish, it is best to mimic their natural environments as much as possible. They live in the rivers of Southeast Asia, with sandy bottoms, lots of plankton, and stray branches and rocks that create natural hiding places.<\/p>\n

What is the best tank for a Rainbow Shark?<\/h2>\n

Although they\u2019re relatively small fish, they require a lot of space. The ideal minimum rainbow shark tank size is 55 gallons<\/a>. This size is recommended for one fish. These fish require big tanks, which translates into heavy tanks when fully filled with water. For this reason, we also recommend purchasing a dedicated aquarium stand<\/a>.<\/p>\n

Tank size requirements will increase depending on the number of other fish you keep in your tank. If you want to keep 2-3 rainbow sharks together, like we recommend, then consider 125-gallon tanks. This size gives them each sufficient space to stake out a territory large enough that they won\u2019t feel the need to constantly defend it.\u00a0<\/p>\n

Long aquariums are best for this fish. Horizontal space is key for making them not feel cramped and super territorial. Long aquariums also give you more room for adding in decorations like driftwood<\/a> and rocks to create more nooks and crannies for privacy. Big tanks weigh a lot so make sure you have a proper aquarium stand<\/a> before purchasing one of these tanks.<\/p>\n

How many Rainbow Sharks can go in my tank?<\/h3>\n

The answer to this question depends on the size of the tank. 55-gallons<\/a> is ideal for one rainbow shark. If you want to keep two or three sharks, 125-gallons is the minimum tank size to consider.<\/p>\n

Water Conditions<\/h3>\n

The first step in establishing ideal water conditions for your red-finned shark is to fully cycle the tank<\/a>. This will ensure your key water parameters, such as ammonia, nitrites, and nitrates, are in-check and able to support your fish. If you add fish without cycling your tank, you will likely kill your fish.<\/p>\n
