Care

Hosereef Gobies are relatively easy to care for but do require a well-established tank with plenty of live rock and sand substrate to thrive. They are bottom dwellers and enjoy sifting through the sand for food, which also helps to keep the substrate clean. A varied diet of meaty foods such as brine shrimp, mysis shrimp, and finely chopped seafood, supplemented with high-quality pellet or flake food, will keep them healthy and vibrant.

Reproduction

In the aquarium, Hosereef Gobies may spawn if kept in a pair or small group, with the male guarding the eggs until they hatch. However, raising the fry can be challenging due to their small size and specific dietary requirements.

Habitat

Istigobius hoesei is found in the Western Pacific, from the Philippines to Australia. They inhabit shallow, sandy areas and reef flats, often seen darting in and out of burrows or hiding among the rocks and rubble. In the wild, they are typically found at depths ranging from just below the surface to about 25 meters.
