Need suggestions for unplanted plants?
I've got a 210 and I can't keep anything planted (my clown loaches seem to dig up anything I try to bury.) I've also got pool filter sand as a substrate and I don't want to tear down the tank to replace it (I wasn't going to do plants, but I can't help myself) Anyway, I'm looking for suggestions on plants that don't need to be rooted. I've got some java fern and some anubias, and was wondering if there were other options? I'd really love some color in there, but I know I'm limited.
Any help would be appreciated (even if someone can point me in the right direction)
