Asterropteryx semipunctata
Family: Gobiidae ยท Gobies
Also known as: Half-Spotted Goby, Starry-Eye Goby, Teal Spotted Goby
The Starry Goby is a charming small species adorned with a constellation of iridescent teal-blue spots scattered across its dark brown to olive body, giving it the appearance of a miniature night sky โ an apt inspiration for its common name. These sparkling spots extend across the head, body, and fins, and are particularly vibrant under blue or actinic aquarium lighting. At just 2 inches maximum, this goby is an ideal candidate for nano and small reef aquariums.
In the wild, the Starry Goby inhabits sheltered reef zones, rubble fields, and seagrass beds throughout the Indo-Pacific. It is a secretive species that spends much of its time in small burrows or crevices among rock and rubble, emerging to forage on tiny benthic invertebrates. This burrow-dwelling habit makes it a fascinating species to observe in the home aquarium, where it will establish a preferred hiding spot and gradually become bolder as it acclimates to its surroundings.
Captive-bred Starry Gobies have been produced by Biota Marine Life, making this previously obscure species more accessible to hobbyists. Captive-bred individuals are hardier and more willing to accept prepared foods than their wild-caught counterparts. The Starry Goby is completely reef-safe and ignores corals and invertebrates. Its peaceful nature and small size make it compatible with virtually any non-predatory community reef setup.
Starry Gobies are carnivores that feed on tiny benthic crustaceans, worms, and zooplankton. In captivity, they accept frozen mysis shrimp, brine shrimp, cyclops, and high-quality micro pellets. Ensure food reaches the bottom substrate where this species primarily feeds.
The Starry Goby is very peaceful and compatible with most reef-safe community species. May be slightly territorial around its preferred burrow but rarely aggressive. Avoid pairing with aggressive bottom-dwelling species that compete for the same hiding spots.
Check CompatibilityStarry Gobies form pairs and deposit eggs within their burrow or crevice. The male guards the clutch until hatching. Biota Marine Life has achieved captive breeding of this species. Larvae require live rotifers and copepod nauplii during the planktonic stage.
