First Oscar tank set up today, the tank was cycled and now i have a few questions. Its a 30 gallon tank with 2 small oscars in it. I know its small but for now its fine. The oscars have a regular painted gravel i treated the water and the filter currently has no carbon or ammonorid. The oscars arent eating my cichlid staples or any flake food and are kinda swimming a little off on there sides. They seem to lay on the bottom by one another. Any Ideas is this normal What should i do?
