There is a wide continum between parrots and the origional shape of midas/sysnpilum. The generally accepted qualification for kkp at least to the people i"ve talked to is that it can close its mouth and has no notch. But then again some say it has to be able to develop a nuchal hump.
heres one of mine.
He has only a small dent in his forehead and has a fully formed mouth. But is he a kkp?
The other day I picked up a parrot with no notch at all, just a perfectly curved forehead like lots of kkp ive seen. but that one dosen't close his mouth all the way (however it can move)
on the other hand, Ive seen lots of "darmo's" (rarefish's kkp) that cannot completeley close their mouths, which are also considered "king kong parrots".
Heres something to read on the topic from happybreed,
probably one of the only "authoritie"s extant at this time on the type of cichlid
http://www.happybreed.com/en/species.htm
Blood Parrot is the earliest defined type of the Cichlid bred, King Kong Parrot is the typical type of Cichlid hybrid at earlier stage, therefore, King Kong parrot has been comparing with latest hybrid Cichlid; but the Blood Parrot¡¦s shape is smaller, with bigger head, more protruding eyes and V-shape mouth; King Kong Parrot has longer size with reddish orange
¡@ colour, dorsal fin are shorterthan anal fin, the shape is similar to the Red Devil, when it grows to the size of 18 cm, the shape of the mouth changes to triangle with more protruding jaw, only 20% of them grow to the size of half kilogram.
of course theirs and my definitions differ slightly. and this is of course because of the differet relationship to the particular breed of fish that our respective cultures each have. I consider the happy breed opinion to be more difinitive in a traditional sense; this explains at least for me why many thai king kongs I've seen have a shape similar to damos with the mouth described by happybreed. Of course many king kongs in america look different, I would imagine it is because most blood parrots in america are bred from later generation blood parrot stock consisting of mostly females paired with males that are F1 outcrossed to a parent species or in some cases just the origional species, midevil or red sysnpilum. This is because of the relative rarity of fertile blood parrot males and the nature of their gene pool.
This is why I believe we see so many blood/king kong parrots here that look like the firsh you and I have. fish that look more like midevils, and who are often just mixes of the species. Given this knowledge, we could assume this the reason why a dfferent set of factors has arisen for the differentiation of "king kong" or "blood" parrot cichlids between oriental and occidental nations. Overall it is just a matter of "branding" and having a brand name, all king kong parrot really is.
Whether you think that fish is a king kong parrot, a blood parrot, or some other kind of short body fader depends on whether you subscribe to the eastern or western colloquial definition of the difference.
Hope that helps : P
I'm currently working on collecting a number of these fish in order to strain them out and develop a breed of "mini midas" that looks like the fish pictured above. IF you or anyone else reading this would like to sell theirs, please PM me. I need females. Female F1 parrot x midas are great too.
