Blackbar Soldierfish
Myripristis jacobus
Blackbar Soldierfish is a nocturnal reef fish found over coral and rocky drop-offs. It shelters by day in crevices and feeds at night on plankton and small benthic invertebrates.
Identification points
- Deep red to orange body with a distinct dark bar or smudge on the side below the dorsal area
- Large eyes adapted to low light, with a laterally compressed soldierfish shape
- Long spiny dorsal fin and rough-looking, armored head typical of soldierfish
Habitat
Reef-associated, usually on steep outer reef slopes, ledges, caves, and crevices from shallow water to deeper reef faces; often forms daytime aggregations under overhangs.
Bait notes
If taken incidentally, small natural baits such as shrimp, squid strips, or tiny cut bait will tempt it; small jigging lures or micro-soft plastics may also draw strikes at night near reef structure.
Behavior
Primarily nocturnal and schooling; emerges after dark to feed on zooplankton and small crustaceans, then retreats to cover at dawn. It is not generally considered a targeted game fish.
Caution
Reef-fish consumption advisories can apply in some tropical areas; local guidance should be checked because ciguatera risk may exist in reef species depending on location. Handle carefully around sharp reef structure.
Fishing notes
Fish after dusk around reef edges, caves, and drop-offs with light tackle and small hooks. Present bait close to structure; catches are usually accidental rather than the result of species-specific targeting.
