Hi, I have a recently set up 75 gallon with 2 medium/ small JD's in it. I also have a 40 gal. with 3 female convict cichlids init. I'm wondering if I would be able to add the convicts to the 75 gallon tank without much problem. Or would the tank be maxed out from the 2 JD's. Finally, if I don't mix the convicts and JD's what else could I put in the tanks for variety?
