Yes I do stand corrected. Planaria must come in many forms I just didn't know that they could...I used to believe that Planaria could be carriers of pests that could adversly affect aquarium fish. The Planaria I feed my fish are totally healthy as I can raise them in my sump just by placing one or two Sword leaves or Almond leaves in there. I doesn't really cost anything to do that and I can get lots of them in just under a week. Then I just discard the leaves before they get too mushy. Hey, I should try crypt leaves to see what happens.
