I currently have an african cichlid with a bunch of barbs and some danios in a 20 Gallon tank. The cichlid will leave the other fish alone giving the occasional chase. Will cories get picked on in this enviornment?
I've got African cichlids and I wouldn't put a cory in with mine - I have one (latin name painisinthebuttis ) that tries to bite me and the syphon everytime I clean the tank. Actually he's an auloncara tricolour - not the biggest in the tank, but definitely "the boss". Most African cichlids are quite aggresive, especially the mbuna and my "clean up crew" in the tank are a large plec and a synodontis euruptis (sp?)
