I bought this plant and I wasn't told what it was, it seems very hardy, and the largest (About 6" tall) looks as though for every sprout of leaves, they have roots dangling down, there are a few of them. The bunch I got came with a few of them, they were really cheap, my Betta and shrimp love them, and I would like to know more about the species, a name is all I need, but more information will help!
