Sorry to get Pedantic on you @LobsterOfJustice , but for posterity, the "Deep water" Coral Beauties typically refer to, the more lightly colored ones; the presumption is the lack of UV penetration doesn't develop as much melanin. Where As OPs might be more accurately described as hypermelanistic if it was a coral beauty. However I think OP's Pic is likely a Yellowfin Angelfish C. flavipectoralisunder blue lighting. Edit: Though the orange lower fins do look Coral Beauty ish when put next to the Yelllowfin.
