Common name: Pacific goby

General information

Sclater's Goby, scientifically known as Callogobius sclateri, is a small and fascinating fish species that is well-suited for nano and small reef aquariums. This species is known for its unique behavior and striking appearance, with a body coloration that blends shades of tan, brown, and white, often with a distinctive pattern that provides excellent camouflage against the sandy and rocky substrates of its natural habitat.

Care

Sclater's Goby is a bottom-dwelling species that prefers aquariums with a sandy substrate and ample rockwork to provide hiding places. They are generally peaceful and can be kept with other non-aggressive tank mates. These gobies are not known to be picky eaters and will accept a variety of foods, including frozen and live meaty foods such as brine shrimp and mysis shrimp. It is important to maintain stable water conditions and avoid aggressive tank mates that may outcompete them for food or territory.

Reproduction

In the wild, Sclater's Goby is known to form monogamous pairs and exhibit biparental care, with both parents guarding the eggs until they hatch. Breeding in captivity is not common, but with the right conditions and a well-established pair, it is possible for hobbyists to observe spawning behavior.

Symbiosis

One of the most interesting aspects of Sclater's Goby is its symbiotic relationship with alpheid shrimp, also known as pistol shrimp. In this mutualistic association, the goby serves as a lookout for the nearly blind shrimp, while the shrimp constructs and maintains a shared burrow that both species use for shelter. This fascinating behavior can be observed in the aquarium if both species are introduced together.

Habitat

Sclater's Goby is found in the Indo-Pacific region, from the Red Sea and East Africa to the western Pacific. They inhabit shallow coastal areas, typically in association with sandy bottoms and coral rubble where they can easily dig and maintain their burrows.
