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!
 
Divider won't do much. The Oscar will see be a douche when the divider comes down.

U would need bigger tank for that Bass...

The average size for kelberi Pbass maxes out at 16" and possibly a couple inches smaller for females (mine's a female). I also most likely will get rid of the oscar when the Pbass hits his size, and she'll be alone in there with the pleco. But then again I'm new to the whole cichla thing so correct me if I'm wrong ;D it's not a temensis that reaches a meter in length atleast XD
 
Is there anyway I can "get rid" of the oscars territory in the tank? Thanks!

In a nutshell...No

If those are the only 2 fish in the tank, one will assert dominance over the other...it's the way they are wired. Also for the size potential of the 2 you have, you wouldn't be able to add other Cichlids to spread the aggression across a pecking order. 1 on 1 somebody is going to get stressed in that tank.

try silver dollars....

Seems like a good Idea. Silver dollars have little bioload. But how many should I put four or so? And what kind, I heard red hook dollars get pretty large so I'm not entirely sure. THANKS!

Max size has nothing to do with a bass in a 120g. They are active open water predators unlike a lot of other cichlids, so need a good deal of swimming space. They also shouldn't be kept with more aggressive cichlids, because they stress very easily. I would separate them or get a much bigger tank.
 
I agree with this.
My rule of thumb with cichlids, is a "minimum" of 10 gallons per inch of adult.
And this really only applies to lazy lurker types, for something pelagic like Pbass, that need room to run, more is not unreasonable.
