What is the basic care for freshwater flounders? I saw those little flat fish in my LFS and eventually, I bought one of them. Some people say that they require live foods, while others say they accept normal aquarium flake foods. I know those fishes like brine shrimps, so I tried to feed him with the O.S.I brine shrimp flakes. He doesn’t seem to be interested of it at all…

I also tried sinking tablets with shrimp content, but the result seems to be the same…

What exactly do they require?
