   Hornwort is a good plant for aquariums with plant eating fish, since the hard leaves do not taste so good!

A rootless plant, Hornwort can be kept floating at the top of the aquarium or buried in the gravel to suit your taste. If you bury Hornwort in the substrate, the Hornwort stems are held in the gravel by root-like organs called rhizoids. The stems will branch off to form nice thickets for fish and especially fry to retreat into. Be careful with it however, because it breaks easily and many of the pieces can become their own plants. Hornwort is an easy plant to care for since

Hornwort can be kept in many aquarium environments, such as coldwater aquariums and tropical aquariums. It is a great aquarium plant for all levels of experienced aquarists. It is also readily available at fish stores or online.

This plant is magnificent. I put it in my 29g and it grew THREE INCHES overnight! I love the way it seems to change shape every day. Sometimes it grows thick collections of branches at the top that look like palm trees. Once it grows too big, you just snip it in the middle, attach a plant weight, and throw it somewhere else. Putting a bunch together makes a lovely bush effect.

Hornwort is a very attractive plant, which groups nicely. It grows readily, even under mildly unstable conditions (Dont use that as an excuse to abuse it). My only warning is dont place this in smaller tanks, because the spine-like leaves constantly fall off of the bottom stems, and grow on the top. The leaves float so are easily removed, but can clump up and slowly rot.

Hornwort is a great plant very easy to care for and it reproduces by itself. A good plant for fry to hide in. But beware usually it brings friends like snails to your tank. Everytime we get some hornwort we are plagued with pond snails you'll see a few and then a week later there is about 50 snails in there. The hornwort grows fast like cabomba and still gets pecked at by the mollies especially fry mollies. I have all kinds of baby fry in my hornwort. A very good all around plant for the aquarium and it does shed its leaves but the decaying matter turns into algae for the pleco. For beginners this is the best plant for you.
