Common name: Periophthalma prawn-goby

General information

The Broadbanded Shrimpgoby, scientifically known as Amblyeleotris periophthalma, is a captivating species popular among aquarists for its symbiotic relationship with pistol shrimps. This small, bottom-dwelling fish is known for its striking appearance, characterized by a series of broad, dark bands across its body, contrasted with lighter interspaces that may have an orange hue.

Care

Amblyeleotris periophthalma requires a sandy substrate in the aquarium to mimic its natural environment, where it can burrow and interact with its shrimp partner. It's important to provide plenty of hiding places and a peaceful tank community, as these gobies can be shy and easily outcompeted for food by more aggressive fish.

Reproduction

In the home aquarium, breeding Broadbanded Shrimpgobies 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 the Broadbanded Shrimpgoby is its symbiotic relationship with pistol shrimps, particularly those of the genus Alpheus. In this mutualistic arrangement, the shrimp maintains and defends a shared burrow while the goby acts as a lookout. The shrimp, which has poor eyesight, relies on the goby for warning signals of approaching danger.

Habitat

Amblyeleotris periophthalma is found in the Western Pacific, from Indonesia to the Great Barrier Reef, and typically inhabits sandy and rubble substrates near coral reefs. They are often observed in depths ranging from 5 to 30 meters.
