Centropyge acanthops. Beautiful fish but more suited to a fish only or non-clam reef tank (clam nipper). Not dwarf dwarf, but more the size of a Lemonpeel or Flame angel.

Very rarely offered fish, far less common than most of the other dwarf angels.
Bought it 3+ years ago from J&L. Really healthy. Never been sick. Great appetite and fun to watch it explore the tank.

Asking $40. Will be available later this week when I shut down the 210g.
