Diet:
Powder Blue Tangs are herbivores and require a diet rich in marine-based algae and seaweed. Offer nori, spirulina, and algae-based flakes or pellets.

Behavior and Compatibility:
This tang is semi-aggressive and may exhibit territorial behavior, especially toward other tangs or fish with similar body shapes.
