The Firefish is one of the more popular fish in the marine hobby. It is a magnificent fish with brilliant coloration, a unique body shape, and unparalleled personality. Also known as the Firefish Goby, Fire Goby, and Magnificent or Fire Dartfish, Nemateleotris magnifica has a yellow head, white anterior, and pinkish to orange-red posterior. The dorsal, anal, and caudal fins are highlighted in black. In addition to its striking coloration, the Firefish Goby is also heralded as a sweet-tempered fish with lots of personality. And, because of its small size, the Firefish Goby makes a great addition to the smaller reef system.
In the wild, the Firefish Goby is usually found in groups hovering over the reef, harvesting planktonic food that drifts by in the current. The docile, Firefish Goby is timid and in the wild, each will have a "bolt-hole" into which it quickly ducks when threatened. In the home aquarium, the Firefish Goby needs multiple safety zones amongst live rock or outcroppings into which it can dart if stressed.
It requires a 20 gallon or larger aquarium with plenty of loose coral rubble as part of the aquascape, and a tight-fitting lid to prevent it from jumping out of the tank. It will rarely become aggressive towards other fish.
