The Firefish Goby, Nemateleotris magnifica, also known as the Firefish or the Fire Dartfish, features a yellow head and a body that gradiates from white to red and a characteristic elongated first ray on the forward dorsal fin. It is a timid fish that is best suited for smaller reef tanks. The Firefish Goby contains a swim bladder which allows it to seem to hover in place. Like other Goby species, the Firefish Goby will often create its own burrow in the sand - sometimes these burrows are shared in a symbiotic relationship with the Pistol Shrimp. Therefore, a tank with plenty live rock, a sandy substrate, and a tightly sealed lid to prevent escapes is recommended. They will eat a carnivorous diet consisting of zooplankton and chopped meaty foods.
