Tropical Hornwort (Ceratophyllum submersum)

Plant is strictly a floating plant, not rooted. Good plant in a starter tank as it is a very fast grower. After about the first month, you will probably want to get rid of it, however.

I bought a bunch of this plant on my last trip to the LFS and planted it in the gravel. 3 Days later, it's almost reached the surface of my high tech! This is the fastest growing plant I have ever known, maybe even as rampant as Algae. However, I am finding it useful for low-light tanks, as not many stems thrive in low-light conditions.

This plant is very messy. As it grows taller, the lower leaves will fall off like pine needles off a christmas tree. It litters the substrate and clogs up my filter intakes. I do like that it is a fast growing plant, even without CO2. I use it mainly as a starter plant to combat algae during the initial phase of a new aquarium but I will be phasing it out soon.

You can just throw some hornwort in your aquarium and it will take over. The leaves tend to fall off. It grows even better with fertilizer and a good substrate. It is actually a floating plant, but it can be planted. It is very bouyant. It has tough needle-like leaves like a pine tree.

I just picked up a couple bunches for my 46g Tanganyikan African setup I have. The cichlids leave it alone, and it looks great. I've got a low light setup that needed a fast growing plant to outcompete the algae for nutrients. The crypts, apons, anubias, and taiwan moss were
just not cutting it.

This plant is indeed one of the fastest plants I have seen. Don't bother planting it, just leave it floating, either attached to a suction cup, or all over the top.

What I have also tried was to attach lead to the plant about 5cm spaces, and within a week it had created a curtain of green all the way to the top.

I now sell offshoots on ebay, at £1 for three 15cm stems.

If you get this plant soon it will take over your tank.
