Common name: Harrison's Shrimp Goby

General information

Harrison's Shrimp Goby, scientifically known as Amblyeleotris harrisorum, is a captivating species popular among aquarists for its symbiotic relationship with pistol shrimps and its striking appearance. These gobies are characterized by their elongated bodies, adorned with a series of vertical stripes that can vary in color from yellow to orange, with a white base color providing a stark contrast.

Care

Harrison's Shrimp Goby requires a sandy substrate in the aquarium to mimic its natural environment, where it can burrow and interact with its symbiotic shrimp partner. The tank should also have ample rockwork to provide hiding places and a sense of security. 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 finely chopped seafood will help maintain their health and coloration.

Reproduction

In the aquarium, breeding Harrison's Shrimp Goby can be a challenge. They are not commonly bred in captivity, and little is known about their reproductive habits in home aquariums.

Symbiosis

One of the most fascinating aspects of Harrison's Shrimp Goby is its symbiotic relationship with pistol shrimps of the genus Alpheus. In this mutualistic association, the shrimp maintains a burrow in the sand that both the shrimp and the goby inhabit. The goby acts as a lookout for predators while the shrimp, which has poor eyesight, provides the goby with a safe home. This partnership is a remarkable example of interspecies cooperation.

Habitat

Harrison's Shrimp Goby is found in the Western Pacific, from the Philippines to Australia. They inhabit sandy bottoms near coral reefs, often sharing burrows with pistol shrimps. In the wild, they are typically found at depths ranging from 5 to 30 meters.
