I'm looking to help statify my tank a bit with some floating top water plants. I have already tried using duckweed, but i have a bit to much top current for it. My friend was telling me theres a regualr house plant that grows a root mat of the top of aquariums and one of his friends whose a breeder uses it fairly extensively though he couldnt remember the name. My lid that i'm building, as i have a rather unusual footprint for a tank, will haev a "shelf" to house pots and other wet footed plants. I've already bought some red mangrove, eevn though it takes years to grow a substancial amount. So any ideas? as far as possible pre-exisiting plant stock i have duckweed and a couple forms of rotala.
