Ok, thank you very much. It seemed like the guy at PetCo knew less about the fish than I did! Petsmart was muuuuuuuuuch better. The mini-sticks also have (not brine) Shrimp and kelp in them as well. We originally bought them for the Ghost Catfish but they refuse to eat them. They dont sink well so I am going to soak them in tank water until the fall down to the bottom of a dish and then feed. That way the other fishies don't get to them! I was also going to pick up some Ghost Shrimp yesterday but they were $0.49 at petco! At PetSmart they are 33 cents. So I am waiting to go to petsmart to get them. I think my fish will like to eat them.Butterfly said:Most emerald Corys are not really corys they are brochis splendens. Corys will pick up the odd flake that hits the bottom but that isn't a good all the time food. The sticks sound like they will be perfect. They also like the occasional veggie wafer. a variety makes sure they get all th vitamins and minerals they need. good luck.
