Behavior

Shares the Zebrasoma body shape — deep and disc-like — with the Yellow Tang and Sailfin Tang. Moderately aggressive toward other tangs, but generally manageable. Rarely seen in the hobby due to its restricted wild range and limited collection.

Diet & Feeding

Herbivore. Offer dried seaweed daily, spirulina-based foods, and quality herbivore pellets. Provide plenty of live rock for natural grazing.

Cautions

Commands a premium price due to rarity. Moderately aggressive toward other Zebrasoma species. Acclimate carefully; wild-caught specimens can be finicky at first.
