Niger Triggerfish (Odonus niger)

The Niger Triggerfish is a striking, deep-bodied reef predator admired for its electric blue-green shimmer, angular face, and flowing lyre-shaped tail. Found across the Indo-Pacific’s outer reef slopes, it is among the more peaceful triggers in the hobby—yet still full of personality. With its expressive eyes, quirky behavior, and vivid coloration, the Niger Trigger adds bold character to larger marine aquariums.

Tank Requirements

A minimum of 125 gallons is recommended, as this species grows large (up to 12 inches) and needs ample swimming room. Provide strong rockwork for shelter and exploration, along with moderate to strong water movement. A secure lid is a must, as triggers can jump and displace lids with their powerful jaws. Best kept in a mature tank with stable parameters and ample territory.

Color, Personality, and Hardiness

Juveniles show brilliant blue-violet tones and grow into darker, iridescent adults with subtle green hues and a signature tail stream. Known for their high intelligence and curiosity, Niger Triggers will often "watch" you and interact with their environment. They are very hardy, disease-resistant, and quick to acclimate—ideal for intermediate to advanced aquarists.

Diet and Feeding

A voracious omnivore with strong jaws, the Niger Trigger requires a varied, meaty diet. Feed a mix of frozen silversides, squid, shrimp, clam, marine pellets, and occasional algae-based offerings. Multiple daily feedings support growth and health. Include shelled foods (like clams or krill) to help wear down their continuously growing teeth.

Tankmates and Behavior

While less aggressive than many triggerfish, the Niger Trigger can become territorial as it matures—especially in tight quarters. Best kept with similarly sized or larger tankmates that can handle its assertiveness. Avoid small, delicate fish and ornamental shrimp. Though not reef-safe in all cases, some individuals coexist peacefully with corals and large inverts in well-managed setups. Exercise caution and monitor closely.
