Gray Poma AngelfishThe Black Velvet Angelfish, also known as the Gray Poma, is predominantly black with a variable sized splash of gray on the head and the horizontal upper half of the body. The tail and posterior tip of the dorsal fin is outlined in yellow. The Black Velvet Angelfish is shy and may be difficult to acclimatize. It needs a tank of not less than 50 gallons with plenty of hiding places. It is not a good reef dweller, since it nips at stony and soft corals
