Yellowfin Goatfish

Mulloidichthys vanicolensis

Yellowfin Goatfish (Mulloidichthys vanicolensis) is a tropical Indo-Pacific goatfish found over sandy and rubble bottoms near reefs. It uses chin barbels to probe for worms, crustaceans, and small benthic invertebrates and is a common small food fish in shallow coastal waters.

Identification points

Bright yellow stripe and yellow lower caudal lobe on the tail
Two distinct chin barbels used for bottom probing
Slender reddish to pink body with a pale belly and small mouth

Habitat

Tropical coral-reef edges, lagoons, seagrass-adjacent sand flats, and outer reef slopes with sand or rubble, usually in shallow water but sometimes deeper offshore over soft bottoms.

Bait notes

Takes small natural baits like shrimp, squid strips, cut fish, and marine worms; tiny soft plastics or shrimp imitations can work when fish are feeding over sand. Use small hooks and light leaders.

Behavior

Feeds by rooting in the substrate with sensory chin barbels, often in loose schools. Active during the day and especially around reefs and drop-offs where small invertebrates are exposed.

Caution

Handle carefully because goatfish have sharp dorsal spines that can puncture. Check local reef-fish consumption advisories in tropical areas, as parasite or ciguatera risk can vary by location.

Fishing notes

Fish near sandy patches beside coral or rubble, letting bait sit on bottom with minimal movement. Light tackle and small offerings are best; they are not usually a premier sport species but can be caught readily on bottom rigs.
