I've got an over abundance of java moss in my 5 tanks, and rather than just peridocally tossing large clumps of it away, I was hoping there might be a better solution that would also add some variety. Are there any tropical fish that eat java moss? In the past 7 years, the only critter I've had that would eat the stuff was one of those 4"-5" red crayfish. However, at the moment, my tanks are a bit crowded to accomodate something that large, but a few 1"-2" plant eating fish would work.
