So what are you saying? Should never keep different species of CA cichlids in the same tank in case they hybiridize. Only species tanks?My sole point is this. Do you want, down the road, to see posts where people put up pics of a fish and the stock response is miterror?
Instead, I would say you should know what you are keeping and shouldn't distribute hybrids!
Just because some people confuse mayan and festae does not mean they cannot be easily distinguished. I've seen all kinds of cichlids confused. Even JD's confused for green terrors; jewel cichlids confused for JD's. The distinction with midas and RD is that they CANNOT be reliably distinguished in captivity.
As long as you know what you have how is mayan or festae any different together then any other CA cichlid?? Of course when people don't know what they have all kinds of cichlid hybrids can be produced and distributed......but that is the same with any cichlids!!
