Hey guys I have a 120 gallon with a overly aggressive 13" oscar and a 8" Kelberi Peacock bass. My oscar doesn't want to stop being a douche and attacks literally anything that crosses his path. And the results are starting to show. My Pbass half the time hides in a corner but still eats perfectly fine and has no trouble getting food. What I want to know is if I put a tank divider for a month would it cease aggression once removed? Is there any other way I can reduce aggression? I know when the peacock bass grows he'll take dominance but that's if he lives to do so! He just has some scrapes on his side because he constantly harasses him but never any deep injuries thankfully. HELP!
