Mimic Half Black Tang

About this fish

Mimic Half Black Tang is a marine tang sold under that shop name, with the scientific name Acanthurus chronixis. Tangs are active reef-safe (species- and individual-dependent) aquarium fish known for grazing on algae and helping keep tank surfaces and live rock tidy. In practice, they’re best used as a centerpiece swimmer in a well-established saltwater aquarium with reliable filtration, ample rock for grazing, and a steady diet that includes algae-based foods.

Features:

• Marine tang for an active, mid-to-large swimming display
• Uses natural grazing behavior—beneficial for algae-coated rock surfaces when available
• Best kept in a mature, stable saltwater system with strong biological filtration
• Generally needs a varied diet with algae and quality prepared foods to support healthy grazing
• Can show territorial behavior toward other tangs; plan tankmates thoughtfully
• Active and alert—often spends time picking at rock and open water swimming routes
