I posted this in the general discussion and someone recommended that I place it here for better answers. First, I have a 75 gallon tank with a 3 in Jag that is at least a year and a half old since that's how long I've had him. Yes, you read that right. 3" in 18 months! I also have a Red Devil/Midas in a 55 gallon tank alone. I got both fish the same day. The RD is about 9 or 10". Awesome fish with a huge nuchal hump. What I'm wondering, is what's the best way to have more than one CA cichlid in a tank? I've tried adding a single specimen with the jag and the jag just goes after whatever I put in. Should I just leave the jag alone? Or could I potentially add a few more fish all at the same time for better luck? What fish could I potentially add to this tank?
