Nope I just sold the whole batch of 30 kribs a month ago. And I have these flowerhorns a while back. Just sharing them with you all. The funny thing is the bigger the bump (kok) the higher quality the fish. So flowerhorns are hybrids between cichlids (the exact fish are still unknown but guesses have been made) so technically you could say it has gotten larger through selective breeding. But even in pure strain cichlids like convicts, green terrors, Red Devils, Midas and frontosa sometimes the males will display this bump in the head.
