Care

Ogasawara Shrimp Gobies are relatively hardy and can be a good choice for both novice and experienced aquarists. They require a sandy substrate to burrow and create their homes. These gobies prefer a tank with plenty of live rock to provide additional hiding places and to support a healthy microfauna population. They are generally peaceful but can be territorial towards their own kind or similar-looking species.

Reproduction

In the aquarium, breeding Ogasawara Shrimp Gobies can be a rewarding experience. They are known to form monogamous pairs and spawn within the safety of their burrows. The male typically guards the eggs until they hatch.

Symbiosis

One of the most fascinating aspects of the Ogasawara Shrimp Goby is its symbiotic relationship with pistol shrimps of the genus Alpheus. The shrimp maintains and defends the burrow while the goby serves as a lookout. The goby's keen eyesight alerts both animals to potential threats, while the shrimp's digging activity provides the goby with a safe haven.

Habitat

Native to the Ogasawara Islands of Japan, these gobies inhabit sandy and rubble substrates in lagoons and coastal reefs. They are typically found at depths where light penetration allows for the growth of benthic algae and seagrasses, which contribute to the structural complexity of their habitat.
