Common name: New Caledonia Shrimp Goby

General information

The New Caledonia Shrimp Goby, scientifically known as Amblyeleotris novaecaledoniae, is a small, bottom-dwelling fish that is highly appreciated in the reef aquarium hobby for its symbiotic relationship with pistol shrimps and its peaceful demeanor. This species is characterized by its elongated body, adorned with a series of vertical stripes that provide excellent camouflage against the sandy and rocky substrates of its natural habitat.

Care

New Caledonia Shrimp Gobies are relatively easy to care for but do require a well-structured aquarium with a sandy bottom and ample hiding places. They are known to jump, so a secure lid is essential. These gobies thrive on a varied diet of meaty foods, including frozen mysis shrimp, brine shrimp, and finely chopped seafood.

Reproduction

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

Symbiosis

One of the most fascinating aspects of the New Caledonia Shrimp Goby is its symbiotic relationship with pistol shrimps of the genus Alpheus. The shrimp maintains a burrow in the sand which both the shrimp and goby inhabit. The goby acts as a lookout for predators while the shrimp works on the burrow. This mutualistic relationship provides the shrimp with a warning system and the goby with a safe haven.

Habitat

Amblyeleotris novaecaledoniae is native to the coral reefs of New Caledonia, where it is typically found in shallow waters. It prefers areas with sandy bottoms where it can easily dig and maintain burrows in conjunction with its shrimp partner.
