I have a “blue gene” jd, and a albino tiger Oscar. Right now they both are housed in separate 55 gallon tanks, due to the fact that their both only about 5 inches long. My question is, could I house these fish together in a 120 or 125 or would they be constantly fighting? I had them together in one 55 for a day because the ac went out and had to move the Oscar out of 100 degree room. During that day the jd seemed to terrorize the oscar, even the the O is a good inch longer, and inch bigger around. Would I still have the same problem in 120 or 125?
