The Scribbled Angelfish, Chaetodontoplus duboulayi, also known as Duboulay's Angelfish, features a  blue/black body with blue edging on its fins, a bright yellow tail, and a thick yellow stripe behind the face and over its mouth. Like many large Angelfish their appearance will change dramatically from the juvenile to adult stage. Due to aggression towards other Angelfish they are best kept singly but will do well with other larger 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.
