I have a 4" peacock bass and a 4" largemouth bass in a tank together with an oscar and the two bass are always fighting. The confusing part is they spend all their time together and even sleep together. Are they just play fighting? They both seem happy and healthy and both eat alot but im concerned because sometimes they get really into it. They dont seem to mark each other up but they will tear up the tank and sometimes they go at it so bad that the oscar (king of the tank at 6") will go in there and break it up. should I be worried or is this just fun for them?
