Small Triplefin Blenny
Tripterygion melanurus
Small Triplefin Blenny (Tripterygion melanurus) is a tiny reef fish of the eastern Atlantic and Mediterranean region, typically found among shallow rocks and algae. It is not a target sport fish; records are sparse, so angling information is limited.
Identification points
- Very small triplefin with three dorsal fins, the first two short and spiny and the third longer and soft-rayed.
- Dark overall coloration with a distinctly dark tail region, especially the caudal peduncle and caudal fin.
- Slender body and bottom-perching posture, usually seen on rocks or algae rather than swimming in open water.
Habitat
Shallow rocky reefs, boulder fields, tide pools, and dense algal growth in clear coastal water, usually close to the bottom and sheltering in crevices.
Bait notes
Not a common angling target. If caught incidentally, very small bits of shrimp, mysis, worm, or tiny soft-plastics on ultralight tackle are the most plausible baits.
Behavior
A small benthic ambush forager that picks tiny crustaceans and other invertebrates from rock and algae cover; males are often territorial around small shelters.
Caution
Sharp rockfish-like spines are not a major issue, but spiny reef fish handling care is still wise; no species-specific consumption hazard is well established, and it is not generally an angling species.
Fishing notes
Best approached with fine ultralight gear near rocks and algae in shallow water; small jigs or micro-soft plastics fished slowly and very close to bottom may take one by accident.
