Jewelled Blenny
Salarias fasciatus
The Jewelled Blenny (Salarias fasciatus) is a small reef-dwelling combtooth blenny found on shallow tropical coral and rocky reefs across the Indo-Pacific. It grazes on algae and detritus, often perching on rocks and coral heads in surge-swept areas.

Identification points
- Mottled tan-brown body with pale speckling and irregular vertical bars
- Long continuous dorsal fin running nearly the full length of the back
- Blunt head with prominent cirri above the eyes and on the nape
Habitat
Shallow tropical coral reefs, rubble slopes, reef flats, and rocky tide-exposed areas with abundant algae; usually on or near the bottom in very shallow water, often around coral heads and ledges.
Bait notes
Not a common target for sport fishing and usually too small to pursue intentionally. If collected, tiny pieces of shrimp, fish, squid, or algae-based baits can trigger strikes; very small micro-jigs or bits of soft plastic may also work.
Behavior
A territorial benthic grazer that spends much of its time perched on the substrate picking at algae and biofilm. It darts into crevices when alarmed and is most active in daylight around hard cover.
Caution
Avoid handling roughly; like many blennies it can nip and has sharp small teeth. Do not eat unless local guidance confirms it is safe and legal, as small reef fishes may carry ciguatera risk in some areas.
Fishing notes
Best approached with ultra-light tackle near shallow reef structure, using tiny hooks and minimal weight. Present bait close to the bottom and keep pressure gentle; many anglers instead observe or aquarium-collect this species rather than fish for it.
