I wonder why people consider the Crabro to be agressive. In Europe, I hardly read reports of agressive Crabro's, but they probably dó become agressive in a tank that is too small (like many cichlids), which is where the problem may be. They look really cute and colourful when they're young, but they grow large (for a Mbuna), and at a considerable rate. Could their feeding behaviour be confused for agressiveness? I believe that in the wild, they feed on parasites (amongst anything else they can get in their mouth). Maybe an 'agressive' Crabro is merely trying to get a snack? I never kept them myself, so feel free to shut me up
, but I just see a very mixed picture on this species and I'd like to find out where the difference comes from.
