What type of damsel is this?

[GuOD]

I thought he's a bluefin damsel but he doesn't look like any of the pics. My LFS has Behns damsel written but that doesn't seem right.

He has changed slightly, his bakc half is white, front is purplish, and the fins are blue front, yellow back. He's getting pretty aggresive towards my 3stripe damsel.

I think it somewhat resembles a marginate or marginated damsel..Dascyllus marginatus

Yellow-tail Demoiselle (Neopomacentrus azysron)? Perhaps juvenile in your picture. The Behns is one of the damsels that is bright when a juvenile, then turns a dull color as it matures. So it's possible that it is a Behns, just a mature adult.
