Most African cichlids will cross with each other but, in my opinion, this is a major part of the reason that quality of african cichlids are hard to find. It is getting really hard to find nice Pseudotropheus & Melanochromis species that look like they are supposed to. Many of these fish show traits of several differant fish. Their colors are lousy, many females have egg spots on thier anal fin, lots of odd shapes now, they don't get a big as the are supposed to. (I could go on for a while here...) Alunocara (peacocks) is all screwed up, several of the varietys being sold don't exist in the wild (how many differant jacofrebergi are available now?) You know that "peach Zebra" being sold in many shops? THat probibly use to be the "Red Zebra" just all pale from non selective breeding. Years ago the common old red zebra was a cool fish, THe females were brilliant bright orange and the males were solid blue, now they suck. I realise that hybreds have thier merrits but I believe that the irresponcipal cross breeding has ruined the quality of many african cichlids.
