My Brazilian pennywort is really doing well in this tank. I started with just a few small 4-6in pieces and now I have a few that are approaching 24 inches long! Straight from the bottom up to the top and over! I really like the floating plant look. Are there other good floating plants? I want stuff to be able to get enough light though. I think I might have seen a couple pieces of duckweed floating in this tank but I don't think I want that, so I took them out. Now I am hoping there aren't any more.
