So I have 2 oscars right now in an 55 gallon tank, the first one is a black tiger Oscar about a year and a half old (4 inches), and the other one is about the same size ( a bit bigger) and I got him/her a couple weeks ago. They first started out as very good friends, not being scared and I haven’t seen them lip lock once. But about a couple days ago, I started seeing the larger(newer) one chasing around the other Oscar, and chasing him into a jar I put in there when he was about 2 inches and he barely fits, just so that he struggles when getting out of the Jar. I call this a “health concern” because he’s not been eating at least when I’m around. Although I have seen him outside the jar during the night. And I see the other (larger) Oscar eating a lot of the food meant for both of them. I have a tank divider but if there’s is another way to make them get along I would really appreciate a response. Thanks!

You cant make territorial cichlids get along. Compounded many times over is the fact that a 55g tank can in no way successfully support 2 Oscars, whether they get along or not. A third concern is that at 4ins and 18 months old, your original fish is 3x smaller than it could or should be. Only solution is to remove one Oscar. Don't consider a divider, extra deco, time outs etc. Your current situation wont work.


I may not be the Boss, but I'm ALWAYS right!

Suprd71 hit the nail on the head... 18 month old oscar @ 4" is way too small... either it is genetically small mutation or stunt... in my experience, more oscar in a big tank reduce the aggression....
