I plan to get a dwarf gourami for my new tank and I've heard they like floating plants. Can anyone tell me what floating plants I can get to put in there?
Personally, I would consider the water sprite or riccia. Riccia will be a little hard to find (at least, in my area) and perhaps messy. Watersprite has a very pretty, soft look to it, too.
For god's sake stay away from duckweed, at least lemna minor. It is a pest and will take over your tank. I had some hitchhike in and am having a horrible time with it.
