Cichlids from lake Malawi or Tanganyika with the exception of shell dwellers do not belong in any tank that is under 4' do to the fact that they are very active and require a good amount of swimming room.
Ok thanks I will keep that in mind. I have never had cichlids before and am having a hard time researching them. Would African Butterfly Cichlids be ok? Anomalochromis thomasi. I would like a fish that could not look too small in the tank though it is probably impossible and unhealthy. Any kind of fish that is colorful and active on its own would be great!
