Hi! I just got a 10gal tank in it i have tropical fishes. I am planning on getting another 10gal and i want to know what cichlid i can put in a 10gal since its small. Are there dwarf cichlids or what kinds dont really grow and stay small. I know my daughter has some kenyi and they seem to not grow. Its been quite sometime and they still look the same. Are kenyi's more agressive than convicts? Pls educate me on this. Thanks.
