The Blue Dartfish, is a reef-associated species with a relatively large distribution across the Indo-Pacific Ocean ranging from the Red Sea to the Tuamoto islands, north to the Ryukyuu islands and south to the southern Great Barrier Reef. The Blue Dartfish is a beautiful fish with a sleek elongated body sporting a soothing iridescent green coloration with subtle blue markings on the head, face, and gill plates. The Blue Dartfish enjoys the company of fellow Blue Dartfish and naturally form shoals comprised of a few individuals to several dozen individual for an impressive display. In the home aquarium, the Blue Dartfish enjoys being in pairs or in small groups and make a wonderful fish for a fish only or reef aquarium.

The Blue Dartfish should be housed in an established 30 gallon or larger aquarium with plenty of loose coral rubble, ample swimming room, and a sandy bottom for burrowing. The Blue Dartfish is somewhat skittish in nature and will quickly dart into a burrow in the substrate if it is startled or senses danger. The Blue Dartfish 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.

The Blue Dartfish feeds mostly on plantonic prey items suspended in the water column but will pick food off the substrate as well. For the home aquarium offer the Blue Dartfish a diet which includes mysis shrimp, brine shrimp, table shrimp, and frozen food preparations for carnivores. The Blue Dartfish should be fed at least three times per day.
