yeh i generally keep amazon swords, java ,anuba and on top i have mix of floating plates mostly water lettuce (grow about 1-2" across) and giant water lettuce (4-8" across) but there is other stuff floating and growing on the top hahaha i just got a load i brought on line and its mixed. i alway have moss balls in my tanks but in this tank i broke them up and tied them to a piece of slate then ties java moss to the top so it's sort of hidden cause the plecs love to rip it up.
i was having issue getting my javas to go at any sort of rate until i started to change my water changes, i also avoid moving them at all once they start growing they seem to take a while but once they start if you move them the slow again. also they grow better with reduced water changes than with fretz added IMPO. the floater control the level well on there own, i have them in every tank even the dovii dont rip them up like everything else lol.
