I have a heavily planted tank that is suffering from a greenish-greyish filament algae. I have noticed that my Platys pick at it a bit, but not enough to really make an impact. I understand that if I cut back on feeding them they will probably make a larger dent, but I'm worried about my other fish. Will Tetras or Gouramis find other things to nibble on if I cut out the flake food. thanks, Wesley Dean
