Can anyone help me identify this colouring and pattern?

Nemesis has a light lavender body (which doesn't show up on the photo well) with blue at the base of the fins fading into turquoise, then oil slick green that shimmers and finally deep velvet red. He had a deep red face that almost looks black. He is much more stunning in real life especially when properly flared but it took me so many attempts to just get a picture that captured the colour of his fins.

Looks like a multicolor :) Maybe has some grizzling.
