This is a standard adult male. Still missing a bit headshape but almost supermale: Photo1 Photo2 Photo list (scroll down in side bar)
Younger and less dominant have less red, some almost none. Often like a band in the tail. Like the fish in the background on aim_foliksta´s photo. There are also some individual variations but not geographic or clearly defined morphs as far as I know. In normal google photo search there are many photos of all main types from dull female to supermale.
