The adult Gray Black Angelfish, which may also be called the Gray Angelfish, has a gray body with dusky blue polka-dots and the same dusky blue highlights on the caudal, dorsal, and anal fins. The face is a clear, pale silvery-gray. The juvenile is black with yellow stripes.
The Gray Black Angelfish is hardy, and can reach a length of 20 inches as an adult. It therefore requires a 250 gallon or larger tank. The tank should contain large amounts of live rock for hiding and grazing. Gray Black Angelfish is prone to nip at stony and soft corals (sessile invertebrates) and clam mantles.
A varied diet should be provided which includes Spirulina, marine algae, high-quality angelfish preparations, and mysis or frozen shrimp.
