The Java Fern is a well-known and favored aquarium plant, known for its low maintenance requirements. This plant is a top pick for many due to its attractive appearance, effortless maintenance, and simple propagation. It is highly recommended for beginners as it is one of the simplest aquatic plants to grow.<\/p>\n
Below, we\u2019re going to discuss everything you need to know about Java Fern. We\u2019ll review their plant varieties, ideal tank<\/a>, habitat, and best fertilizers<\/a> so that you can safely include these beautiful plants in your aquarium. Both your eyes and your fish will thank you!<\/p>\n Java Fern is scientifically known as Microsorum Pteropus. It is native to Southeast Asia and typically grows in the freshwater rivers and streams in Thailand, Malaysia, India, and China.\u00a0<\/p>\n It has two main methods of grow \u2013 full submersion and partial submersion. However, the roots need to stay submerged in water in order to survive.<\/p>\n Structurally, there are three main parts on the plant:<\/p>\n Java Fern is a traditional green aquarium plant<\/a>. The color can range from medium to dark green with the darker greens associated with high light tanks. The plants can get big, with heights of about 14 inches and 6-8 inches in width.\u00a0<\/p>\n Java Fern is highly adaptable for a variety of tanks, ranging from low light to high light tanks, large community tanks to show tanks.<\/p>\n Below is a breakdown of popular aquarium varieties. Many more versions exist but these are what you will most commonly aquarium when shopping for plants:<\/p>\n As you might be able to guess, Narrow leaf Java fern has thin, narrow leaves.<\/p>\n Even more pronounced than Narrow Leaf, Needle Leaf has even thinner leaves. Most beginner aquarists are shocked the first time that they see Needle Leaf Java Fern as it is not easy to identify as a Java Fern because of how much it visually differs. Needle Leaf is less common than the other varieties.<\/p>\n Named after the Greek god of the sea, Poseidin, the Trident Java Fern has leaves that are forked with several extensions coming off the main leaf. This is thought to resemble the Trident carried by Poseidin.\u00a0<\/p>\n Windel\u00f8v leaves resemble a regular Java fern until it gets to the ends, which separates into finely branched leaf tips.<\/p>\n Overall, the Java Fern is a hardy, easy-to-care-for aquarium plant. It doesn\u2019t require high light or special nutrients, which makes it an excellent beginner\u2019s plant. It is also slow-growing which means that it will slowly expand in your tank, which is encouraging that you\u2019re providing the right conditions, without completely overwhelming your tank quickly.<\/p>\n Much like fish or aquatic critters, aquarium plants thrive when their aquarium settings closely mimic their natural surroundings. In its natural environment, Java Fern grows alongside streams and is often found near moving water, which translates to it favoring some moving water within your aquarium.\u00a0<\/p>\n Typically, your filter set-up will provide enough movement and oxygen. Additionally, Java Ferns don\u2019t need C02 set-ups in order to thrive which simplifies the planted tank set-up.\u00a0Java Fern also doesn\u2019t draw nutrients from the substrate so your choices of substrate (or lack thereof) are endless.<\/p>\n For tank size, the absolute minimum tank size is 10 gallons. While Java Ferns grow slowly, their potential size long-term is large, which can lead to crowding issues in smaller tanks.<\/p>\n \t\t<\/p>\n \n\t\t\t\tOur Pick\t\t\t<\/p>\n \t\t<\/p>\n \t\t<\/p>\n \t\t\t\t\t<\/p>\n \t\t\t Most lighting set-ups will support the Java Fern. However, the best set-up would be subdued fluorescent or incandescent bulbs. It is a low-light plant and can survive with light levels that quickly equal a death sentence for other aquarium plants.<\/p>\n Ideally, Java Fern requires about 2 watts of light for each gallon in your tank, using 5000-7000K bulbs. Therefore, if you have a 50 gallon tank, you\u2019d need at least 100 watts of light.<\/p>\n Fertilizer<\/a> can generally be skipped with Java Ferns. They truly are simple aquarium plants.<\/p>\n However, if you\u2019re interested in speeding up the growth, adding in a liquid fertilizer like Seachem Flourish<\/a> or API Leaf Zone<\/a> will do the trick. While the Java Fern won\u2019t grow at the same rate as your other plants, you will definitely start to see a quick increase in the growth pace.<\/p>\n \t\t<\/p>\n \t\t<\/p>\n \t\t<\/p>\n \t\t\t\t\t<\/p>\n \t\t\t \t\t<\/p>\n \t\t<\/p>\n \t\t<\/p>\n \t\t\t\t\t<\/p>\n \t\t\t Java Ferns will tolerate both cold water<\/a> and tropical tanks, with a preferred temperature range between 68-82oF. The recommended pH is 6.0 \u2013 7.0 with a hardness of 3 \u2013 8dGH.<\/p>\n Java Ferns are incredibly flexible plants and can basically be added to your tank in almost any location. They\u2019re not dependent on light or substrate which means that you, as the aquarium owner, can get really creative!<\/p>\n In order to plant them, you need to weigh them down or tie them to the location where you want them to stay. Otherwise, it will just float around your tank and end up somewhere less ideal than your chosen location.\u00a0<\/p>\n Most aquarists tie it to a rock<\/a> or piece of wood to get it planted, using fishing line or a string. The rhizome, or subterranean stem, will then send out roots that attach the plant to the object. This process usually takes a few weeks. Once the roots are intact, you can safely remove the fishing line or string and the plant should stay put. If not, repeat the previous step for an additional few weeks.<\/p>\n Try to avoid burying the rhizome in your substrate, as that can cause it to rot. If you put the rhizome next to some gravel, it will send the roots out and they will encircle the gravel. As long as they hold on to enough gravel, this gravel ball can function as a weight that allows you to move the Java Fern around the tank. This is a good trick if you don\u2019t have any other potential anchors in your tank.<\/p>\n No surprise here \u2013 Java Ferns are easy on the maintenance front. Leaves will occasionally die over time. When that occurs, pinch it off as close to the rhizome as possible and remove the dead leaf. Plant maintenance complete!<\/p>\n Besides that, don\u2019t expect your Java Fern to immediately start growing. It may take some time to adjust to your tank conditions and establish its rhizomes. Once both of these changes occur though, it will start growing.<\/p>\n Your plant will need some manicuring<\/a> to achieve the planted tank look you\u2019re seeking. Prior to planting, you need to consider if you want to keep your plant small or let it grow big and bushy. If you want to keep your plant on the smaller side, you will need to remove the small new plantlets that develop on the leaves. If you\u2019re going for a bushier, less-manicured style, just let the plant keep growing. Leave the new plantlets to grow to achieve a bushier effect.<\/p>\n Expect to prune<\/a> about once a year. Cut the leaves as close as you can to the rhizome so the plant understands the leaf is gone and it can redirect the energy to the remaining leaves.<\/p>\n Java Fern should not be planted in substrate, as it will rot the rhizome and eventually kill the plant.\u00a0<\/p>\n Java Fern melt is another known issue. Multiple leaves can start to turn yellow or brown, get mushy and die. This is very common when added to a new tank so it is advised to trim any browning leaves down the rhizome. As the plant becomes acclimated, it will begin to start putting out new leaves.<\/p>\n In established tanks with established plants, this issue can happen for a few reasons. Common reasons are the plants don\u2019t have enough nutrients (start using fertilizer), there is too much light (reduce the light or move the plant to a shadier part of the tank), or if there is too much blue-green algae in your tank (add some algae eaters<\/a> to help).\u00a0<\/p>\n Sometimes, new Java Fern owners will see rows of dark spots on the underside of leaves. This is not disease. Actually, it is quite the opposite! It means the adult plant is about to put off plantlets with each spot becoming a baby plant.<\/p>\n Avoid plants with browned leaves. You want the leaves to be bright to dark green.<\/p>\n Check out the rhizome too. You\u2019re looking for a dark green rhizome without browning.<\/p>\n Java fern is typically sold as a cutting from a larger plant. You might only get a few leaves attached to a rhizome. While it might look kind of spindly, this is completely normal and the plant will soon put off new leaves as the plant matures.<\/p>\n Like most things Java Fern, plant propagation, or the growing of new plants, is a pretty simple process.<\/p>\n When plantlets (baby plants) start to form, wait until they have formed several leaves and trailing roots. You can then remove them from the parent and treat them like new Java Ferns in your tank. Tie them to a piece of driftwood<\/a> or rock and start the process over again. Because they\u2019re already acclimated to the tank conditions, they will grow faster than purchasing a new Java Fern.<\/p>\n For an alternative method, you can snip off a piece of rhizome with a few leaves attached. Each piece will become a new plant. Then, repeat the process over again by tying them down in the tank.<\/p>\n Soon, you will have more Java Fern than you know what to do with!<\/p>\n The theme of this care guide is \u201cJava Ferns are easy to care for!\u201d This section of the guide is no different.\u00a0<\/p>\n Java Ferns are compatible with most aquarium fish as apparently, Java Ferns are not too tasty. Further, they have a tough, leathery leaf structure which makes them difficult to consume. Even most plecos<\/a> will leave them alone.<\/p>\n A word of caution when the Java Ferns are young, as larger, more aggressive fish can knock them over and damage them. It is best practice to attach them to something heavier like a rock or piece of driftwood<\/a>.<\/p>\n No, Java Ferns do not need to be planted in substrate. Planting the rhizome in substrate will likely cause it to rot. The rhizome will send out leaves and roots to attach to whatever is near it. Therefore, you can tie your Java Fern to driftwood<\/a> or rocks and it will eventually attach its roots to the object, which will keep it from floating off.<\/p>\n Yes, Java Fern is good for aquariums and aquarists alike. It is slow-growing and easy to grow and reproduce, which makes it very popular<\/strong>. Additionally, <\/strong>Java Fern tolerates most lighting conditions and many water conditions. It will add natural beauty to your tank and provide a nice refuge for your fish and aquatic critters to hide.<\/p>\n No, Java Fern is a slow-growing aquarium plant compared to many other species. This is a benefit of the plant, as it won\u2019t quickly overtake your tank. In high light and CO2 situations, it grows fast. creating about a leaf a week, or slightly less. In low light and CO2 situations, it only creates about one leaf a month.<\/p>\n Make sure that your Fern gets plenty of light, but not for more than 10 hours a day. It doesn\u2019t need super strong lights. Ideally, it needs about 1.5 to 2 watts of light for each gallon in your tank, using 5000-7000K bulbs.<\/p>\n In terms of aquarium plants, yes, the Java Fern is low light. It needs about 1.5 to 2 watts per gallon in your tank.<\/p>\n Because <\/strong>Java Ferns are slow growing, they can take a while to securely attach in your tank, especially in a low light and CO2 tank. In those situations, it could take 3-6 months for the plant to be fully and securely attached.<\/p>\n The leaves will be vibrant green, the plant will be growing, and eventually, will start propagating new plants. If the plant has brown, mushy leaves, while failing to grow and create new plantlets, your Java Fern is likely unhealthy. In these situations, you will want to evaluate your lighting, CO2<\/a>, and fertilizer requirements. Additionally, you should pinch off any dead leaves near the rhizome in order to help the plant reroute energy to the healthy leaves.\u00a0<\/p>\n Yes, Java Ferns can get too much light. When receiving too much light, they are susceptible to leaf scorching and overabundant algae growth. Both of these issues can harm the long term health of the plant.<\/p>\nRecommended Java Fern Care Items:<\/h3>\n
