Galápagos Gregory
Stegastes arcifrons
The Galápagos Gregory is a small damselfish endemic to the tropical eastern Pacific, especially around the Galápagos and nearby islands. It is territorial and usually seen in shallow reef zones where it grazes and defends a small patch of habitat.
Identification points
- Small damselfish with a compact, laterally compressed body
- Dark body marked by thin pale blue lines forming arc-like markings on the head and upper body
- Often seen hovering just above shallow reef rock or coral while defending a small territory
Habitat
Shallow rocky and coral reef margins, surge channels, and algal-covered reef flats in tropical eastern Pacific island waters, typically very near shore in clear sunlit shallows.
Bait notes
Not a standard angling target and is rarely pursued intentionally. Small pieces of shrimp or fish on fine tackle may take one if targeted, but catch-and-release is preferable.
Behavior
Highly territorial, often hovering close to shelter while defending a feeding patch. It grazes mainly on filamentous algae and may chase intruders away from its territory.
Caution
Handle carefully around reef structure to avoid cuts from sharp coral and spines; this species is not a common food fish and is not typically targeted for consumption.
Fishing notes
If encountered while reef fishing, use tiny hooks, light line, and minimal bait; it is more commonly observed by divers than caught. Avoid destructive reef contact and release promptly.
