I would love to have a planted tank, however, I have 2 silver dollars who love to eat them. I make sure they have plenty of romaine lettuce, and algae wafers, but they still nibble on almost any plant I've tried. The only success I've had is with banana plants! I love them, the fish don't eat them, but I have a 90 gl. tank, which needs more than a few banana plants to achieve the look that I'm going for! I've tried all the plants that the Internet sites have suggegested to no avail. I'm hoping that one of you guys can solve my problem.........Kris
