Powder blue tang- Acanthurus leucosternon

The Powder Blue Tang is one of the most visually stunning tangs in the saltwater hobby — a fish that genuinely stops people in their tracks. Its powder-blue body is perfectly complemented by a bold yellow dorsal fin, stark white-accented black face mask, and vivid yellow-tipped tail, creating a color combination that pops brilliantly under reef lighting. While it requires experienced care and pristine water conditions to thrive, the reward of keeping a healthy, vibrant Powder Blue Tang in a well-maintained reef is second to none.

Care Notes:

• Tank size: 100+ gallons with ample open swimming space and strong water flow
• Reef-safe: yes — completely safe with corals and invertebrates
• Best suited for experienced reef keepers — sensitive to water quality and highly susceptible to ich and other external parasites; quarantine is strongly recommended before introduction
• Diet: primarily herbivore — offer nori, algae sheets, and algae-based pellets daily; supplement with frozen mysis and quality pellets; grazes actively on live rock algae
• Can be aggressive toward other tangs, particularly similar-looking species — introduce as the last tang and into a large, well-established system
• Thrives in high-flow, well-oxygenated systems that mimic its natural reef-crest habitat
• One of the most sought-after tangs in the hobby — worth every bit of the care it demands
