Finescale Triggerfish
Balistes polylepis
The finescale triggerfish (Balistes polylepis) is a coastal reef-associated triggerfish of the eastern Pacific. It is a powerful, armored predator that feeds on hard-shelled invertebrates and is more often encountered by divers than targeted anglers.

Identification points
- Deep, laterally compressed triggerfish body with a small mouth and large head
- Rough-looking scales with fine, reticulated patterning that gives the species its name
- First dorsal spine that can lock upright like other triggerfishes
Habitat
Shallow coastal reefs, rocky bottoms, kelp-edge areas, and adjacent sandy patches in the tropical to subtropical eastern Pacific, usually near structure from very shallow water to around 50 m.
Bait notes
Small pieces of crab, shrimp, squid, clams, or shellfish work best. Tough baits fished on bottom near rocks or reef edges are more effective than fast-moving lures; small jigs tipped with bait can also draw strikes.
Behavior
Bold and territorial, it cruises reef edges and bottom structure and crushes crabs, mollusks, and sea urchins with strong jaws and teeth. It may nibble baits carefully before committing and can be stubborn once hooked.
Caution
Sharp teeth and strong jaws can bite fingers during handling. As a reef fish, it may be subject to local regulations and size limits; check area rules before keeping any.
Fishing notes
Fish tight to structure with abrasion-resistant leader and a small, strong hook. Slow bottom presentations and short casts near reef edges are best; be ready for abrupt power runs into cover and use steady pressure to keep it clear.
