The Firefish (Nemateleotris magnifica), also known as the Fire Goby, Magnificent Fire Fish, or Fire Dartfish, is a species of dartfish native to coral reefs of the Indian and Pacific oceans.

Distribution and Habitat

The Firefish inhabits parts of the Indian and Pacific oceans. It occurs as far west as the East African coast to as far east as the Hawaiian Islands. Within the Pacific Ocean it occurs as far south as the Austral Islands to as far north as the Ryukyu Islands of Japan. It can be found at depths of 6 to 70 meters on coral reefs.

Physical Description

The Firefish reaches a maximum length of 9 cm (3.5 in). It has a bright yellow head merging into a white body gradually shading into a red-orange tail. The dorsal fin is very long and the fish flicks it back and forth as a signal to conspecifics.

Diet and Feeding

The Firefish feeds on small invertebrates. In captivity it feeds on brine shrimp, mysis shrimp, and sometimes zooplankton. It should be fed two times per day.

Behavior and Reproduction

It is usually found just above the bottom facing into the current where it awaits its prey. Adults occupy sandy burrows alone or in pairs while juveniles live in small groups. These fish are monogamous and will retreat to burrows if threatened.

Aquarium Care

It is considered reef-safe and peaceful. It is suitable for novice marine fishkeepers. It requires a tank of at least 20 gallons with a tight-fitting lid as they may jump from the water. They will form schools if many are put into the same tank.

Conservation Status

Classified as Least Concern by the IUCN Red List.
