Humpnose Bigeye Bream

Monotaxis grandoculis

Humpnose Bigeye Bream (Monotaxis grandoculis) is a reef-associated marine fish of the Indo-Pacific, often over coral and rubble near lagoons and outer reef slopes. It is caught incidentally by coastal anglers and is not usually a primary sport target.

Identification points

Prominent raised forehead or hump in front of the eyes
Very large eyes relative to head size
Silvery to pale body with yellowish fins and a stout bream-like shape

Habitat

Tropical marine coral reefs, reef flats, lagoon edges, and rubble slopes from shallow inshore reef areas to deeper outer-reef habitats.

Bait notes

Take small cut baits, strips of squid, prawns, and reef fish flesh; small bottom jigs and soft plastics also work. Use modestly sized hooks and natural presentations near structure.

Behavior

Commonly forages near the bottom on benthic invertebrates and small reef prey, often in loose groups or as solitary fish. It is more active around structure and feeds over reef surfaces, especially at dawn and dusk.

Caution

Like many large reef fish, it may carry ciguatera risk in some tropical areas; avoid eating large reef-caught individuals from known risk regions. Sharp dorsal spines and reef abrasion can cause injury.

Fishing notes

Fish it on light-to-medium bottom tackle close to coral edges, drop-offs, and rubble pockets. A slow drift, anchored berley line, or short lift-and-drop presentation near the seabed is effective; handle carefully around reef cover.
