Common name: Chocolate surgeonfish

General information

The Mimic Lemon Peel Tang, scientifically known as Acanthurus pyroferus, is a captivating species popular among aquarists for its dynamic coloration and interesting behavior. Juveniles exhibit a bright yellow coloration with blue accents around the eyes and dorsal fin, closely resembling the Lemon Peel Angelfish (Centropyge flavissima), which is thought to be a form of mimicry for protection against predators. As they mature, their coloration transitions to a darker brown with a distinctive orange patch on the flank, giving rise to another common name, the Orange Shoulder Tang.

Care

Mimic Lemon Peel Tangs require a spacious aquarium with plenty of swimming room and live rock for grazing on algae. They are active swimmers and can become territorial, so it's important to introduce them to the tank last to minimize aggression. A varied diet of marine-based seaweed and algae, along with meaty foods, will ensure proper nutrition and health.

Reproduction

In the wild, Acanthurus pyroferus forms large spawning aggregations, and reproduction occurs through pelagic spawning where eggs and sperm are released into the water column. In the home aquarium, breeding is rare, but maintaining optimal water conditions and providing a stress-free environment can encourage natural behaviors.

Habitat

Mimic Lemon Peel Tangs are found in the Indo-Pacific region, from the eastern coast of Africa to the central Pacific Ocean. They inhabit coral-rich areas and clear lagoons, typically at depths ranging from the shallows down to about 25 meters. They are often observed grazing on algae-covered substrates and are known to be quite active during the day.
