Hi, Me and my roommate just bought a tiger oscar and have some questions. It is bout 2 inches and we have it in a 30 gallon tank for now. We are planning on upgrading to a 75 gallon for it but we just haven't had the money to get a new tank yet. Our oscar just seems to be floating and not really eating, we have tried bloodworms and flakes and it just won't eat, none the less really swim around. Is this normal for when you first bring an oscar home? Just wondering if anyone who has kept oscars in the past can help us and give us some more tips on keep our little buddy alive.
