Common name: Horse-shoe shrimp-goby

General information

The Highfin Shrimp Goby, scientifically known as Amblyeleotris arcupinna, is a captivating and relatively small fish that is popular among aquarists for its symbiotic relationship with pistol shrimps and its striking appearance. This species is characterized by its elongated dorsal fin, which is where it gets its common name. The body is typically tan with orange stripes, and the high dorsal fin is often adorned with dramatic spots and markings.

Care

Highfin Shrimp Gobies are considered moderate in terms of care. They thrive in well-established aquariums with a sandy substrate that allows them to burrow and create shelters. These gobies prefer a tank with plenty of live rock and hiding places. They are generally peaceful and can be kept with other non-aggressive tank mates. A varied diet of meaty foods such as brine shrimp, mysis shrimp, and prepared foods is recommended to maintain their health and coloration.

Reproduction

In the aquarium, breeding Highfin Shrimp Gobies can be a challenge. They are not commonly bred in captivity, and little is known about their breeding habits in the wild. However, they are thought to form monogamous pairs and lay eggs in burrows, which are then guarded by the male.

Symbiosis

One of the most fascinating aspects of the Highfin Shrimp Goby is its symbiotic relationship with pistol shrimps, particularly those of the genus Alpheus. The shrimp maintains and digs the burrow while the goby serves as a lookout for predators. This mutualistic relationship provides the shrimp with a warning system, while the goby gets a safe haven.

Habitat

Amblyeleotris arcupinna is found in the Western Pacific, from the Philippines to northern Australia. They inhabit sandy and rubble substrates in coral reef environments, often at depths ranging from 5 to 30 meters. Their natural habitat includes areas with access to burrowing spaces and sufficient cover to evade predators.
