ok the neon tetras just spit it back out. was hoping the snails would and sucker fish would enjoy. I will try 2 tablespoons... the cory's were not interested either... maybe they are spoiled too, i feed flake, insect pellet, dehydrated blood worms, shrimp pellets, betta floating food, and alage wafers. I already lost my clown pleco so i was hoping this would help...
