Care

Nocturnal Gobies are relatively easy to care for but do require a tank with a sandy bottom where they can exhibit their natural sifting behavior. They are not aggressive and can be kept with other peaceful fish and invertebrates. A varied diet of meaty foods and marine pellets will help maintain their health and coloration.

Reproduction

In the home aquarium, breeding Nocturnal Gobies can be a challenge. They are not commonly bred in captivity, and little is known about their breeding habits in the wild. However, they are known to spawn in a cave or crevice, laying eggs that are guarded by the male until they hatch.

Habitat

Amblygobius nocturnus is found in the Indo-Pacific region, from the Red Sea to Samoa, and from the Great Barrier Reef to Micronesia. They typically inhabit shallow lagoons and reef flats, often found at depths of 1 to 12 meters. In the aquarium, replicating their natural environment with live rock and a sandy substrate can provide them with the necessary habitat to thrive.
