Description
*This fish is a marine species*
The Fire Goby (Nemateleotris magnifica), also known as the Firefish Goby or Fire Dartfish, is a vibrant and peaceful marine species prized for its striking colouration and calm nature. Native to coral reefs throughout the Indo-Pacific, this goby features a white anterior body that gradually shifts into brilliant orange and red tones toward the tail, with an elegant elongated dorsal fin that it raises when alert or threatened.
Known for its shy but curious behaviour, the Fire Goby is a favourite among beginner and experienced marine aquarists alike. It occupies the lower to middle levels of the aquarium and is often seen hovering near the substrate or darting quickly into rock crevices when startled.

The best aquarium size for Fire Goby
A minimum aquarium size of 40 litres is sufficient for a single Fire Goby. A larger tank of 75 litres or more is recommended for a bonded pair or when housed with other small reef species. Ensure the aquarium has a tight-fitting lid, as Fire Gobies are known jumpers.
Tank Mate Compatibility for Fire Goby
This species does best with other small, peaceful reef inhabitants. Suitable tank mates include:
• Clownfish
• Royal Gramma
• Banggai Cardinalfish
• Cleaner Shrimp Goby
• Neon Goby
Diet for Fire Goby
The Fire Goby is carnivorous and benefits from a protein-rich diet. Feed small portions 1–2 times per day, including:
• Frozen mysis shrimp
• Enriched brine shrimp
• Finely chopped seafood
• Marine micro pellets and flakes
A varied diet ensures strong immune health and vibrant coloration.
Aquarium Setup Fire Goby
Aquarium Filtration
Moderate to strong filtration is required to maintain high water quality. A hang-on-back filter or nano protein skimmer is ideal for smaller tanks. Stable water conditions are critical, as the species is sensitive to ammonia and nitrate spikes.
Aquarium Plants
Live marine plants are rarely used with Fire Gobies. Instead, use macroalgae such as Chaetomorpha or soft corals to provide visual enrichment and aid nutrient control.
Aquarium Lighting
Moderate lighting is sufficient. Fire Gobies do not require intense lighting and may seek shaded areas during peak intensity hours.
Aquarium Heating
Maintain water temperature between 24°C – 27°C using a reliable heater with built-in temperature control. Sudden shifts can stress this species.
Aquarium Substrate
A fine sand bed is ideal, allowing natural burrowing and foraging behaviours. Avoid coarse gravel which can damage the goby’s skin and fins.
Aquarium Decorations
Provide ample rockwork and crevices to mimic natural reef shelter. Fire Gobies need secure hiding places to retreat to when threatened. Open swimming space is also important for their hovering behaviour.
