Nemateleotris magnifica
Family: Ptereleotridae ยท Dartfish & Firefish
Also known as: Firefish, Fire Goby, Fire Dartfish, Magnificent Dartfish
The Firefish Goby is one of the most beloved and universally recommended reef fish in the marine aquarium hobby, prized for its stunning coloration, peaceful temperament, and captivating hovering behavior. Its elegant body features a gradient that transitions from a pale white or cream head through yellow and orange on the midsection to a vivid red or magenta on the posterior half and tail. An elongated first dorsal spine flicks constantly, giving the fish a characteristic flagging motion as it hovers face-first into the current.
In the wild, Nemateleotris magnifica is widespread across the Indo-Pacific, from the coast of East Africa to Hawaii. It inhabits outer reef slopes and drop-offs, typically at depths of 6 to 70 meters, where it hovers above the reef face in the current, picking zooplankton from the water. When threatened, it darts backward into a burrow in the reef substrate with lightning speed. Pairs are common and typically share a burrow, emerging together to feed during calm conditions. The species' tendency to bolt into hiding at the slightest perceived threat makes it appear timid, but in a calm aquarium environment, it becomes bold and constantly visible.
The Firefish Goby is an ideal fish for beginners and experienced hobbyists alike. Its hardy constitution, willingness to eat a variety of foods, completely reef-safe nature, and peaceful temperament make it one of the best all-around marine aquarium fish. The primary husbandry concern is its notorious jumping behavior. Firefish will leap through any available gap when startled, making a tightly sealed aquarium absolutely essential. Egg crate or mesh coverings over any openings are recommended. Keep singly or as an established pair, as unpaired individuals may fight in the confines of an aquarium.
Firefish Gobies are planktivores that feed exclusively on zooplankton in the wild. In captivity, they eagerly accept frozen mysis shrimp, enriched brine shrimp, cyclops, and finely chopped seafood. They can be trained to accept high-quality marine pellets and flakes over time. Multiple small feedings throughout the day are preferable to one or two large feedings. Vitamin-enriched foods help maintain their vibrant coloration.
The Firefish Goby is extremely peaceful and gets along well with virtually all non-aggressive marine species. Excellent tankmates include clownfish, chromis, gobies, blennies, wrasses, and other dartfish species. Avoid housing with aggressive or territorial fish that may bully the Firefish into permanent hiding. Do not keep two unpaired Firefish together, as they will fight, sometimes to the death. Completely reef-safe with all corals and invertebrates.
Check CompatibilityFirefish Gobies form monogamous pairs that share a burrow. Spawning occurs within the burrow, and the male guards the eggs until hatching. Successfully breeding Firefish in captivity is challenging, primarily due to the difficulty of raising the tiny pelagic larvae which require rotifers and other microscopic foods. Establishing a bonded pair can be done by purchasing two individuals and allowing them to pair naturally in a calm environment.
