Overview

Provide a 150 litre or larger reef tank with sand and rock and a very tight lid, since dartfish are champion jumpers, kept at 23 to 27 C and pH 8.1 to 8.4. It is reef safe and eats zooplankton, so feed mysis, enriched brine shrimp, and pods. It is peaceful and shy at first, and it can be kept singly or in a small group in a larger tank with enough burrow sites.

In the wild

The blue hana goby is a pale blue dartfish with iridescent blue face markings and long trailing filaments on the tail. It hovers in open water just above a sand burrow, snapping at plankton and dropping into the burrow when startled. It is a graceful, active swimmer that likes some current. Long tail streamers give it the alternate name filamented dartfish.

Good to know

Ptereleotris hanae is a dartfish in the family Ptereleotridae. The trailing caudal filaments, usually two to six of them, are a distinctive feature of this species. Like other dartfish it shelters in a sand burrow that it may share with a partner.

Did you know

The long filaments streaming from its tail flutter as it hovers, which is how it earned the name filamented dartfish.
