The firefish goby is a 3-inch-long, yellow-headed aquarium fish with a white body and an orange-red tail. Firefish, fire dartfish and magnificent dartfish are other common names for the firefish goby.
The firefish goby is an exceptionally timid fish, and it feels most secure when living alone with a single mate or in an aquarium that holds at least 20 gallons of water. These fish are known to leap from their tanks when startled. For this reason, the aquarium must have a cover. Firefish gobys love meaty food and thrive on a diet that includes brine shrimp, Mysis shrimp or frozen seafood.
