Can I separate my 2 oscars they have been together for 3months and that oscar is the one that's always bothering the rest of the fish while the other one don't care about nothing.
maybe take him out, although then the other oscar will pick on the fish. maybe get a tank divider for the mean one, but then the other oscar will be the dominant fish so unless a fish is about to die or never comes out because of the one, then dont worry about it, but if other fish are getting hurt then try out a tank divider. best of luck!
