I find it hard to believe that the overseas wholesalers and our wholesalers/importers brought in pure interruptus as johanni without knowing? Surely if they were interruptus they would have been identified as such from the beginning? Mind you stranger things have happened.
I too would like to see some pics of your fish Navarre, it would be awesome to have another pure melanachromis species in NZ! Noone here jumps on anyone else's fish just to rubbish them, were all sick of hybrids and crap fish being spread around, everyone here is trying to help and also give people what they believe to be correct ID, noone will be worried about anyone discussing that point Maybe were mistaken, or maybe you are either way we all learn and hopefully benefit from it.
The pic posted looks nothing like the pictures I have seen of interruptus the whole body shape and everything looks off.. I dont know if it is the pic or anything because as ive said earlier I have never kept this fish.
Maybe to end this discussion we could get some pics of Navarre's fish (assuming we have decided on the ones on this link) and link them to cichlid-forum, then we would have the opinion of 100's of cichlid fanatics who have most likely kept and bred interruptus and can make a better id?
