Fanbelly Leatherjacket
Monacanthus chinensis
Fanbelly Leatherjacket (Monacanthus chinensis) is a small, laterally compressed filefish of tropical Indo-Pacific waters, often found around reefs, rubble, and seagrass. It is not a major gamefish, but it can be caught incidentally with light tackle and small baits.

Titik pengenalan
- Deep, strongly compressed oval body with a small mouth and pointed snout
- Skin covered in rough, sandpapery bony plates rather than scales
- Tall first dorsal spine over the head and a pale fan-like belly/ventral profile typical of the species
Habitat
Shallow coastal tropical and subtropical habitats, especially coral and rocky reefs, reef flats, lagoon edges, seagrass beds, and rubble areas; usually near structure in sheltered water.
Nota umpan
Small pieces of prawn, shrimp, squid, or cut bait on light rigs; tiny soft plastics or small, natural-looking lures can work when fished slowly near structure. It is usually an incidental catch rather than a targeted species.
Tingkah laku
Generally slow-moving and structure-oriented, feeding on small benthic invertebrates and algae picked from the bottom or hard surfaces. It can be wary and may nip baits from cover rather than chase actively.
Berhati-hati
Handle carefully because leatherjackets have a sharp dorsal spine and rough skin; avoid touching the spine area. Not a commonly targeted table fish, and local consumption advisories should be checked before eating any reef-associated catch.
Nota memancing
Use ultra-light tackle and small hooks; present baits close to reef, weed, or rubble and keep the retrieve or drift slow. A quiet approach helps, as the fish can be cautious around shallow cover.
