Purple Firefish

The elegant firefish or purple firefish, Nemateleotris decora, is a dartfish Purple Firefish, also are known as Purple Dartfish, Flame Firefish, Decorated Dartfish, Elegant Firefish, and Fire Goby.

The Purple Firefish was discovered in 1972 in the Maldives.  It is a magnificently colorful little fish. These fish begin with a light-lavender colored body with bold purple markings on their face and towards their tailfin.  Their name(s) come from the dark red and purple colored fins. The Purple Firefish has an elongated first dorsal spine that rocks up and down. These little fish display a lot of personality and should be kept in a tank with generous amounts of rockwork. The Purple Firefish likes lots of crevices, caves, and overhangs where they can “hang” in place. These fish prefer to be kept in pairs and do well in the home aquarium. They are great for reef tanks and will accept most fish foods.

This species is popular for adapting to home aquariums very quickly and living and thriving in small aquariums of 35 to 110 litres in size. Purple Firefish are also popular for being very disease tolerant and hardy with little no special housing requirements beyond a sandy substrate and some live rock present to create their burrow near. Added at the same time, groups of Purple Firefish will also do well in small groups or pairs.

The ideal aquarium should have plenty of hiding rooms at the bottom rock-structure.  Also provide a sand-bed of at least two inches in depth. When startled or threatened, Purple Firefish have been known to jump out of uncovered aquariums. Always keep the tank covered and secured. Provide many hiding places for safety and a sense of security.

The Purple Firefish Goby is a carnivore and eats zooplankton, finely chopped small crustaceans, live & frozen brine shrimp, mysis shrimp, algae, spirulina flakes and other quality flake foods. Gobies ignore corals and are unable to eat most small crustaceans.  This means Purple Firefish are reef safe
