Chocolate-Yellow Mimic Tang: The Chameleon of the Reef

The Chocolate-Yellow Mimic Tang (Acanthurus pyroferus), or Mimic Surgeonfish, is one of the most fascinating fish available to hobbyists, famous for its ability to mimic other species. As a juvenile, it adopts the coloration and patterns of unpalatable Dwarf Angelfish (Centropyge species) to deter predators. The juvenile coloration is typically a vibrant yellow or two-toned mix. As it matures, the fish transitions into a beautiful adult with an overall rich, dark brown or black body and striking yellow accents on its face, gills, and fins, particularly around the eye. This species is an excellent algae-grazer and is fully reef-safe, making it a highly desirable addition for controlling nuisance algae. While generally peaceful, like all surgeonfish, it can be territorial towards other tangs, especially those of a similar shape. A large tank with plenty of live rock for grazing is essential for its long-term health.

Why the Chocolate Mimic Tang is a Great Choice:

• Unique Mimicry: Its ability to change color and mimic other fish makes it a captivating, evolving centerpiece.
• Algae Control: It is a voracious algae-grazer, helping to keep your live rock and glass clean.
• Fully Reef-Safe: It will not harm corals or sessile invertebrates.
• Hardy Species: Tangs are generally robust and resilient once acclimated to a large, well-established aquarium.
