---XR---;2564731; said:correct term is nuchal humps (kok refers to FH's) and both males and females get them, they are more prodominant on male fish though.
most midas get them, and they are common in species from the amphilophus genus.
Nuchal hump whether on FH or any other CA/SA is KOK(slang name). They type of hump on a frontossa or a texas cichlid is referred to as cranial hump.
