The Firefish (Nemateleotris magnifica) is a popular fish in the marine hobby, largely due to its magnificent coloration, unique body shape and unparalleled personality. The Firefish goes by many common names, including; the Firefish Goby, Fire Goby, Magnificent Dartfish and Fire Dartfish. In addition to its striking coloration, the Firefish has a personality to match. Aggression is limited-to-non-existent, except between members of its own species. Therefore, these fish should be kept alone or in mated pairs.
Due to its small size, the Firefish makes a great addition to the smaller reef system. Firefish require an aquarium 37 litres (10 gallons) or larger with moderate lighting conditions and a moderate current passing over the live rock “reef.” Keep in mind that a stressed Firefish will attempt to jump out of your aquarium. Therefore, Firefish should be housed in aquarium systems with a lid. Hobbyists who use a halide system with an open top should construct a Plexiglas “edge” around the trim, at least 25cm (10”) tall. The Firefish should be provided with multiple ‘bolt-holes’ into which it can dart if stressed. Therefore, ample live-rock structure is a must.
Along with algae and zooplankton growing in the aquarium, the diet of the Firefish should consist of finely chopped small crustaceans, vitamin-enriched brine fish (live or frozen), mysis shrimp and prepared foods.
