The Half Black Angelfish, Centropyge vroliki, features a bicolor combination of a pearly white front half fading to a black back half with highlights of orange around the gills and eyes. Due to aggression towards other Angelfish they are best kept singly but will do well with other fish.
They are not reef safe, as they will nip at soft and stony polyp corals, sessile invertebrates and clam mantles. Diet should include a variety of spirulina, marine algae, high quality angelfish preparations, mysis and brine shrimp, 3 times daily.
The picture doesn’t do this fish justice. Mine has blue around anal fin.
