Common name: Starry goby

General information

The Starry Goby, Asterropteryx semipunctata, is a small and attractive fish species that is well-suited for peaceful community aquariums. Its body is elongated with a pattern of white spots on a dark background, resembling a starry night sky, which is the origin of its common name. This species is relatively hardy and can be a good choice for both novice and experienced aquarists.

Care

Starry Gobies are bottom dwellers that prefer aquariums with plenty of live rock and a sandy substrate where they can sift for microfauna. They are not aggressive and can be kept with other peaceful tank mates. A varied diet of meaty foods, such as brine shrimp, mysis shrimp, and finely chopped seafood, will help maintain their health and coloration.

Reproduction

In the wild, Asterropteryx semipunctata is known to spawn in small crevices or under rocks. In the aquarium, breeding is possible but not commonly reported. If conditions are right, they may lay eggs in a secure location, which the male will guard until they hatch.

Habitat

Starry Gobies are found in the Indo-Pacific region, from the Red Sea and East Africa to Samoa, north to the Ryukyu Islands, and south to the Great Barrier Reef. They inhabit shallow reefs and lagoons, often seen hovering above the substrate or resting on coral branches.
