Planehead Filefish
Stephanolepis hispida
Planehead Filefish is a small coastal filefish of seagrass beds, reefs, and weedy shallows in warm waters. It feeds on algae, small invertebrates, and other benthic foods, and is mostly of minor interest to anglers.
Identification points
- Laterally compressed, boxy filefish body with a steep forehead/short snout profile
- Rough, sandpapery skin with a long first dorsal spine that lies flat when not raised
- Mottled brown to olive body often marked with pale spots and irregular scribbles, blending with weeds and reef
Habitat
Shallow tropical and subtropical coastal waters, especially seagrass meadows, algal flats, mangrove edges, and coral or rocky reef margins; often holds near floating weed or structure.
Bait notes
Small pieces of shrimp, squid, clam, or crab can take it; tiny soft plastics, flies, and algae-colored jigs may also work when fish are feeding in weed or around structure.
Behavior
Generally slow and deliberate, picking at algae, hydroids, sponges, and tiny crustaceans; can be territorial around cover and is often seen hovering close to vegetation or reef relief.
Caution
Spiny dorsal and anal fin rays can prick careless handling; handle with caution. Not commonly kept for food, so local regulations and consumption advisories should be checked before retention.
Fishing notes
Use light tackle and small hooks near seagrass edges, docks, mangroves, and reef margins. Present baits slowly and close to cover; it is not usually targeted as a primary game fish.
