Sailfin Tang
Zebrasoma veliferumAlso known as Pacific Sailfin Tang, Purple Sailfinned Tang, Sailfin Surgeonfish, Ringed Tang
Sailfin tangs command attention on the reef with their towering, sail-like dorsal and anal fins that double their apparent size when fully flared. Their bodies are adorned with striking vertical bands of yellow, charcoal, and white, which help them blend into the sun-dappled shadows of coral branches. These active herbivores spend their days constantly grazing on filamentous algae, performing a vital service by keeping coral reefs clean and healthy.

- Observe Fin Display: Look for territorial displays where they flare their massive dorsal and anal fins.
- Keep Distance: Do not corner them against rocks, as they may use their sharp tail spines defensively.
