Care

Hana's Dartfish are relatively hardy and suitable for most reef aquariums. They require a tank with plenty of live rock for hiding and a sandy substrate where they can retreat if frightened. These fish are jumpers, so a tight-fitting lid or screen is essential to prevent escape. They thrive in stable water conditions and do well on a varied diet of meaty foods, such as brine shrimp, mysis shrimp, and finely chopped seafood.

Reproduction

In the wild, Ptereleotris hanae are known to form monogamous pairs and spawn within the safety of their burrows. The male typically guards the eggs until they hatch. While breeding in captivity is less common, providing a stress-free environment with plenty of hiding spaces can encourage spawning behavior.

Habitat

Hana's Dartfish are found in the Western Pacific, from the Philippines to northern Australia. They inhabit coral reefs and lagoon environments, often seen hovering above the substrate or nestled within the crevices of rocks. They are typically found at depths ranging from 6 to 60 meters.
