The Threadfin Dartfish originates from the rubble zones of Cebu. They have an elongated body, which is pale blue or green in colour, with a long flowing split tail. In the wild, this species commonly inhabits the burrow of pistol shrimp, but they do not seem to interact. They enjoy being in pairs, and make a wonderful fish for a fish only or reef aquarium. 

The Threadfin Dartfish should be housed in a 30-gallon or larger aquarium with plenty of loose coral rubble, and requires ample swimming room with a sand bottom for burrowing. It may try to jump out of the aquarium or other small opening, so a tight-fitting lid is required. Rarely will it become aggressive towards other fish. 

It feeds mostly on prey suspended in the water column, but will pick food off the substrate as well. The Threadfin Dartfish feeds on a diet which includes mysis shrimp, brine shrimp, table shrimp, and frozen food preparations for carnivores. It should be fed at least daily.
