Dusky Gregory
Stegastes nigricans
Dusky Gregory is a territorial damselfish of shallow coral reefs and lagoon margins, often defending a small turf-algae garden. It is small, bold, and usually seen close to branching corals or rubble in clear tropical water.

Identification points
- Small dark brown to dusky gray damselfish body
- Faintly paler bars or mottling on the flanks
- Rounded tail and a blunt damselfish profile
Habitat
Shallow coral reefs, reef flats, lagoon edges, and sheltered rubble zones; commonly associated with branching corals and areas where it cultivates turf algae.
Bait notes
Not a targeted game fish and rarely worth active bait fishing. Tiny shrimp pieces, fish scraps, or micro jigs may draw strikes, but it is best considered an incidental catch.
Behavior
Highly territorial and aggressive for its size, especially around its algae patch. It grazes turf algae and small benthic invertebrates, and repeatedly chases intruders from its home range.
Caution
Handle carefully around coral to avoid cuts; reef habitat is fragile and may be protected. As a small reef fish it is not a common food species, so consumption is generally uncommon.
Fishing notes
If caught at all, use very light tackle and small hooks near reef structure; a stealthy presentation is more effective than heavy bait. Release promptly to minimize reef damage and stress.
