Hey guys, I'm looking some advice on floating plants. Currently I have a salvinia sp. (i think) in my tanks. I've tried duckweed, but its a major PITA. I'm looking for something nice looking without super long roots. Is this just wishful thinking. Currently I have found: Azolla caroliniana Phyllanthus fluitans (i prefer this one atm) available from tropica. Are there any others to consider, and is it worth the trouble and money getting them?
