For my 55gal, i would like to try to add one more pair of breeding cichlids if possible?I thought about gbr's but im worried that there would be to much aggression?Heres what i plan to do:I think i have a pair of bolivians already!So im going to take the lone ram back and im either going to add hillstream loaches or kuhli loaches and im going to take the oto out and put him in another tank.Then i would like to add some sort of easy breeding cichlid.This is were i need your help.Thanks!
