The Lemonpeel Angelfish is a cheery yellow with sky-blue highlights on the lips, encircling the eyes, on the pectoral fins, and the tips of the dorsal, caudal, and anal fins. To avoid confusion with the False Lemonpeel Angelfish (C. heraldi) that lacks the blue highlights, this angelfish is also referred to as the True Lemonpeel Angelfish.
The Lemonpeel Angelfish requires a 70 gallon or larger aquarium with hiding places and large amounts of live rock to graze on the microalgae growth. It is very prone to nip at large-polyped stony corals and clam mantles. It is best not to keep Lemonpeel Angelfish with fish of the same genera.
The diet of the Lemonpeel Angelfish should includeSpirulina, marine algae, high-quality angelfish preparations, mysis or frozen shrimp, and other meaty items. This angelfish requires more algae and seaweed in its diet than most angels.
