Common name: White-spotted shrimp-goby

General information

The Mauritian Shrimp Goby, scientifically known as Cryptocentrus leucostictus, is a small, bottom-dwelling fish that is popular among aquarists for its interesting behavior and compatibility with other peaceful tank inhabitants. These gobies are known for their distinctive white spots and tan to yellowish body coloration, which provides excellent camouflage against sandy substrates.

Care

Mauritian Shrimp Gobies are relatively easy to care for but do require a well-established tank with a sandy bottom to mimic their natural environment. They are not aggressive and can be kept with a variety of other peaceful fish and invertebrates. A diet of meaty foods such as brine shrimp, mysis shrimp, and finely chopped seafood is recommended.

Reproduction

In the aquarium, Cryptocentrus leucostictus has been known to form monogamous pairs and spawn. The male typically guards the eggs until they hatch. Breeding these gobies in captivity can be challenging but rewarding for experienced hobbyists.

Symbiosis

One of the most fascinating aspects of the Mauritian Shrimp Goby is its symbiotic relationship with pistol shrimp of the genus Alpheus. The shrimp maintains a burrow in the sand that both the shrimp and goby use for shelter. The goby acts as a lookout for predators while the shrimp works on the burrow. This mutualistic relationship is a remarkable example of interspecies cooperation.

Habitat

C. leucostictus is found in the Western Indian Ocean, particularly around Mauritius and the Reunion Island. They inhabit shallow lagoons and reef flats, often associating with sandy substrates where they can easily dig and maintain their burrows.
