Purple Tang
Zebrasoma xanthurum
Purple Tang is a vivid Indo-Pacific surgeonfish, prized in reef aquariums and occasionally encountered on coral reefs and lagoon slopes. It grazes on algae and is known for its bright purple body and yellow tail.
Identification points
- Solid purple body with a distinctly yellow tail
- Deep, disk-like Zebrasoma body profile with a pointed snout
- Single dark-edged dorsal and anal fin margins with surgeonfish-style caudal spine
Habitat
Shallow coral reefs, reef flats, and lagoon slopes in the Red Sea and western Indian Ocean, especially around hard coral and algae-covered rock.
Bait notes
Not a targeted game fish and seldom taken on bait. In aquarium or observational contexts, it responds to algal foods and herbivore flakes; it is not typically caught with conventional angling gear.
Behavior
Diurnal grazing herbivore that patrols reef surfaces picking filamentous algae and benthic growth. Usually solitary or in loose groups; can be territorial toward other surgeonfish.
Caution
Has a sharp caudal spine like other surgeonfish that can cut if handled. Reef organisms may be subject to local harvest restrictions; do not eat unless local authorities and the source are certain, as reef fish can carry ciguatera in some areas.
Fishing notes
If encountered in reef-fishing areas, avoid targeting this ornamental species. It is best observed on snorkel or dive; collection is often regulated or restricted depending on local laws.
