What is hornwort? It looks like a nice plant for my guppies and I'm using low-light so it's perfect. I heard that they are of the same family with mosses; the kinds that grow in moist places and doesn't grow too big. Can I find them just around?
Or do they live underwater or in pet shops?

Thanks in advance!

I have some, They are very nice. Its an underwater plant, low light. It can be planted or left to float.I got mine in petsmart.

But they do grow big, though. You'll have to keep hornwort trimmed, getting rid of the scraggly parts as time goes on. They have one advantage as a plant, though -- they secrete an enzyme that discourages the growth of blue-green algae, which very few scavengers eat.
