Yeah, the Auratus is going to rule that tank. Auratus are probably the most aggressive african cichlids I've ever dealt with. I have Jewels right now with some Zebras and some others that are basically similiar to Zebras and they are doing great. However, they are by far the most antisocial of all the africans I've ever dealt with. They just don't come up to the glass and swim around constantly as the other types of cichlids. IMO
I would take the Auratus back and get some zebras, I think you'll be much happier.
By the way those CAE
are going to become snacks in an African Cichlid tank.
