Blackbar Damselfish
Plectroglyphidodon dickii
Blackbar Damselfish is a small reef damselfish found on shallow coral and rocky reefs in the Indo-Pacific. It is strongly territorial and usually stays close to branching corals where it feeds on benthic algae and tiny invertebrates.
Identification points
- Dark vertical black bar behind the head/through the eye area
- Bluish-gray to olive body with a paler underside
- Small damselfish shape with continuous dorsal fin and rounded tail
Habitat
Shallow coral reefs, reef flats, and surge-exposed rocky areas with abundant branching coral or shelter, typically in clear tropical saltwater.
Bait notes
Rarely targeted. Tiny hooks with bits of shrimp, squid, or worm can take it when fishing near reefs, but small algae-based or micro-particle baits are more consistent with its feeding habits. Small reef jigs or flies may also get reaction bites.
Behavior
Highly territorial and site-attached; adults defend small patches of reef and graze algae, while juveniles shelter closely in coral heads. It is not a target game fish and is usually caught incidentally.
Caution
Handle carefully; reef habitat can cause cuts and punctures. Avoid standing on or touching coral while fishing. Follow local reef and marine park regulations, as many coral-reef areas restrict collection or fishing.
Fishing notes
Fish very light tackle close to reef structure or coral heads. Short casts and slow presentations work better than distance fishing. Because it is small and reef-bound, most encounters are by accident while fishing for other reef species.
