I just change my 33 community tank to a rocky lake malawi set up and I have 6 Pseudotropheus species(in my sig) and 1 auratus. What do you guys think, I got the guy in my LFS pick this guys out and he said that as long as they are put in the tank the same time there should be no problem... It's true for now and all my fish seems to school together, but would I have problems with agrresion when they reach adult size
