Question, I have a new Oscar that was much smaller than I expected on delivery. (2”) I have had him in with my 7” Oscar, separated in a breeding net, but now he is getting to big for the net, but not big enough to be free with his tankmate. Would it be ok to put him in a 40 gal tank with three African cichlids? The cichlids are about 4” each, and the baby Oscar is about 3”.
