Indian Bullethead Parrotfish
Chlorurus sordidus
Indian Bullethead Parrotfish (Chlorurus sordidus) is a reef-dwelling parrotfish of tropical Indo-Pacific waters, common on coral and rubble habitats where it grazes algae and scrapes turf from hard substrate. It has a robust beak-like mouth and often changes sex from female to terminal male.

Identification points
- Bulky oval body with a steep, blunt forehead in the bullethead form
- Small beak-like dental plate made from fused teeth
- Typically gray-brown to greenish with a paler belly and no long filamentous fins
Habitat
Shallow coral reefs, reef flats, lagoons, and seaward reef slopes, usually over live coral, algal-covered rock, and rubble from the shallows to roughly 30 m.
Bait notes
Not a common targeted game fish and is usually taken incidentally by handline or small reef tackle. Small pieces of shellfish, squid, or crab on light gear may tempt it, but reef grazing behavior means artificial lures are rarely effective.
Behavior
Primarily diurnal and constantly forages on benthic algae and detritus, using its fused teeth to scrape and bite substrate. It often rests in reef structure at night and can be wary in clear shallow water.
Caution
Reef fish consumption can carry ciguatera risk in some locations; local advisories matter. Its fused teeth are not dangerous, but handling can damage the fish and the reef, and local collection rules may protect reef herbivores.
Fishing notes
If targeting for food where legal, fish very light tackle near reef edges and bommies with small hooks and minimal terminal gear. Expect cautious bites; use short fluorocarbon leaders and avoid heavy disturbance of the reef.
