Common name: Black-spotted sand-goby

General information

The Speckled Sand Goby, scientifically known as Istigobius nigroocellatus, is a small and attractive fish that is well-suited for reef aquariums. This species is known for its distinctive black spots and speckled body, which provides excellent camouflage against the sandy bottoms it inhabits. They are generally peaceful and can be kept with a variety of other reef-safe fish.

Care

Speckled Sand Gobies are bottom dwellers that prefer aquariums with plenty of live sand and rockwork to sift through and hide in. They are not demanding in terms of care, but they do require a stable environment with good water quality. These gobies are carnivorous and should be fed a diet of meaty foods such as brine shrimp, mysis shrimp, and finely chopped seafood.

Reproduction

In the wild, Speckled Sand Gobies are known to form monogamous pairs and exhibit biparental care. They lay their eggs in burrows or under rocks, and both parents guard the eggs until they hatch. In the aquarium, breeding is possible but not common, and a well-structured environment with ample hiding places is essential for encouraging reproductive behavior.

Habitat

Istigobius nigroocellatus is 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 sandy areas and seagrass beds adjacent to reefs, typically at depths of 1 to 30 meters.
