Pinktail Triggerfish

Melichthys vidua

Pinktail Triggerfish (Melichthys vidua) is a reef-associated triggerfish of the tropical Indo-Pacific, often seen in small groups near outer reefs and lagoons. It feeds on algae, zooplankton, and small benthic invertebrates, and is sometimes caught incidentally by reef anglers.

Identification points

Deep, laterally compressed triggerfish body with a small mouth and leathery skin
Dark body with a distinctive pink to magenta tail patch/caudal fin coloration
Teeth and dorsal/anal fin shape typical of triggerfish, with the first dorsal spine functioning as a trigger

Habitat

Coral and rocky reefs, reef slopes, outer reef edges, surge channels, and lagoon drop-offs in warm tropical marine waters, usually over hard bottom with good current.

Bait notes

Small pieces of squid, shrimp, fish strips, or marine worms can take them; small reef jigs, micro jigs, and small soft plastics also work when they are actively feeding. Light terminal tackle helps on finicky fish.

Behavior

Diurnal and wary; commonly cruises in loose groups and picks at plankton and benthic food in the water column or just above reef structure. It can be territorial around feeding areas and may dart into cover when pressured.

Caution

Reef fish consumption can carry ciguatera risk in some tropical areas; check local advisories before eating. Handle carefully because triggerfish can bite and their dorsal trigger spine locks sharply when raised.

Fishing notes

Fish light tackle with small hooks and subtle presentations near reef edges, current seams, and drop-offs. Drift baits or work tiny jigs through the upper water column; avoid heavy pressure that spooks them into structure.
