Common name: Flag-tail shrimp-goby

General information

Yanoi's Shrimp Goby, scientifically known as Amblyeleotris yanoi, is a captivating species appreciated by aquarists for its symbiotic relationship with alpheid shrimps and its striking appearance. These gobies are characterized by their elongated bodies, adorned with a pattern of alternating light and dark bands, which provide excellent camouflage against the sandy and rubble substrates they inhabit.

Care

Yanoi's Shrimp Goby requires a well-established aquarium with a sandy bottom to mimic its natural environment. They are generally peaceful and can be kept with other non-aggressive tank mates. Providing a burrow or similar structure is essential, as it allows the goby to engage in its natural behavior of maintaining a burrow, which it often shares with a shrimp partner.

Reproduction

In the aquarium, breeding Yanoi's Shrimp Goby can be challenging. They are not commonly bred in captivity, and little is known about their specific breeding habits. However, like many gobies, they are likely to spawn within their burrows, with the male guarding the eggs.

Symbiosis

One of the most fascinating aspects of Yanoi's Shrimp Goby is its symbiotic relationship with pistol shrimps of the genus Alpheus. The shrimp maintains and digs the burrow while the goby stands guard, alerting the shrimp to danger with subtle body movements. This partnership allows the shrimp to focus on burrow maintenance without the constant threat of predators, while the goby benefits from a safe haven.

Habitat

Yanoi's Shrimp Goby is found in the Western Pacific, from the Ryukyu Islands to Australia. They typically inhabit sandy and rubble areas near coral reefs, often at depths ranging from 5 to 35 meters. Their preference for living in burrows makes them a unique addition to any reef aquarium that can provide a similar environment.
