Mimic Eibli Tang: A Striking Algae Grazer for Your Reef

Discover the unique Indian Ocean Mimic Surgeonfish, a fascinating tang known for its juvenile coloration mimicking a dwarf angelfish before maturing into a handsome, diligent algae eater.

Overview

The Mimic Eibli Tang (*Acanthurus tristis*) is a captivating surgeonfish known for its remarkable appearance. Juveniles display a striking pattern of orange stripes on a beige body, expertly mimicking the *Centropyge eibli* angelfish for protection. As they mature, their coloration shifts to a more subdued yellowish-brown to dark brown, often with a grayish head and lunate tail edged in white. These active grazers constantly pick at algae, making them a valuable addition to a mature marine aquarium.

Care Level

This species is considered of moderate care level due to its specific needs for tank space and diet. While generally peaceful with most non-tang tankmates, the Mimic Eibli Tang can exhibit aggression towards other tangs, especially conspecifics or similar body shapes. It is best kept as the sole *Acanthurus* species in all but the largest systems. Provide ample hiding spots and ensure proper acclimation for a healthy aquarium fish.

Tank Essentials

A minimum tank size of 400 litres is required for this active surgeonfish, though larger is always recommended to accommodate its swimming needs and minimize aggression. Maintain stable water parameters: pH 8.1-8.4, temperature 22-27°C. A well-established aquarium with strong water flow and plenty of live rock for grazing is crucial for their well-being and to facilitate natural behaviors.

Diet

As a primarily herbivorous species, the Mimic Eibli Tang requires a diet rich in marine algae. Supplement their grazing with high-quality algae flakes, pellets, and dried seaweed (Nori) offered several times daily. While they may consume some meaty frozen foods, their immune system and overall health depend on a robust vegetable intake.
