So i have a 75g with africans that i want to change. I have a new home for the african cichlids. I was going to get another Oscar and keep him by himself in the 75. But then i was thinking of a GT(which ive never owned) and since they dont get as big as O's, keep my Red Jewel with him. Is this a good idea? Or should i keep the GT alone also? Thanks for any input.
