Wow.
Just, ummm..., WOW.
Koran Angel = "Pomacanthus semicirculatus".
Just the name indicates a species with semi-circles.
They really called that a Koran?
Seriously?
You can't fix stupid I guess.
But you can let it play with a plastic bag...
BTW:
Koran used to be one of my favorite fish. Not very pretty as an adult, but absolutely gorgeous as a juvenile, and very attitudinal, which is what I prefer.
