Common name: Barehead goby

General information

The Baldheaded Prawn Goby, scientifically known as Amblyeleotris gymnocephala, is a distinctive species of goby that is popular among aquarists for its symbiotic relationship with pistol shrimps. This small fish is characterized by its elongated body, muted coloration with a series of vertical stripes, and a unique bald appearance on its head, which lacks scales.

Care

Baldheaded Prawn Gobies are relatively hardy and suitable for most reef aquariums. They require a sandy substrate to burrow and hide, which is essential for their well-being. These gobies are peaceful and can be kept with a variety of other non-aggressive tank mates. They thrive on a diet of meaty foods such as brine shrimp, mysis shrimp, and finely chopped seafood.

Reproduction

In the aquarium, reproduction of Baldheaded Prawn Gobies is rare but possible. They are known to form monogamous pairs, and if conditions are right, they may spawn in the safety of their burrows. The male typically guards the eggs until they hatch.

Symbiosis

One of the most fascinating aspects of the Baldheaded Prawn Goby is its symbiotic relationship with pistol shrimps of the genus Alpheus. The shrimp digs and maintains a shared burrow while the goby stands guard, warning the shrimp of approaching predators. This mutualistic relationship provides the shrimp with a lookout, and in return, the goby gets a safe haven.

Habitat

Baldheaded Prawn Gobies are found in the Western Pacific, from the Philippines to Australia. They inhabit sandy and rubble substrates in lagoons and coastal reefs, often at depths of 5 to 30 meters.
