Jerry, watch where you send your email. The only people that don't know aren't on the list. Tomoko, I use duckweed and najas (i believe this is some sort of elodea sp.) the fish really love the najas, it provides great hiding space and grows like a weed. It does root itself but mostly floats through the water column.
