This started about 2 or 3 weeks ago by now but I have had these Oscar’s in a 120 for about 10 months to a year now and everything has been great. About 2-3 weeks ago the larger red Oscar started fighting the lemon and beat it up pretty good. I removed the aggressor and put in a “time-out tank” while I went a little over board in adding a bunch of visual blocks and decor in the main tank. I put the aggressor back in the tank and instant fighting again. I have a 180 I’m currently building a stand for. Will the larger tank help with aggression or do I need to rehome or is this breeding?
