Niger Triggerfish

The Niger Triggerfish, *Odonus niger*, is a captivating and active addition to a large marine aquarium. Known for its striking coloration, which can range from deep blue to purple with vibrant blue or green highlights, and its distinctive crescent-shaped tail, this triggerfish is a popular choice for experienced hobbyists.

A minimum tank size of 180 gallons is recommended to provide ample swimming space and accommodate its potential adult size of up to 12 inches in captivity. The aquarium should be equipped with plenty of live rock and sturdy decorations to create hiding places and territories, as Niger Triggerfish can be territorial, especially towards conspecifics and other triggerfish. While generally considered less aggressive than some other triggerfish species, they can still be boisterous and may nip at smaller, less robust tank mates. They are not considered reef-safe as they will readily consume invertebrates, including crustaceans, mollusks, and echinoderms.

The Niger Triggerfish is a carnivore and its diet should consist of a variety of meaty foods. Offer a mix of high-quality marine pellets, frozen foods such as mysis shrimp, krill, and chopped seafood like squid and fish. Providing foods with shells, such as occasional whole shrimp or clams, can help wear down their continuously growing teeth.

There are no readily apparent visual differences between male and female Niger Triggerfish. Breeding in a home aquarium is extremely difficult and has not been widely documented.
