Years ago I raised and breed African Cichlids and now I am wanting to start with a new species. I just purchased a GT and currently have a small tank, I think a 25 gallon, with a Jewel Cichlid. I put the Gt in the same tank and know I need to move the Gt. Can I house the 2 in 75 gallon tank? The Jewel is very aggressive. Also what can I house with the GT once I move to the 75 gallon? The GT is not eating flake food. Should I jump to blood worms. The GT is about 2".
