Common name: Saddled goby

General information

The Clitellate Goby, scientifically known as Callogobius clitellus, is a small and fascinating fish species that is a member of the goby family. This species is known for its distinctive saddle-like markings and its ability to form symbiotic relationships with certain invertebrates. They are not as common in the aquarium trade as other gobies, but they can make a unique addition to a reef tank due to their interesting behavior and compatibility with other peaceful tank mates.

Care

Clitellate Gobies are relatively hardy and can adapt to life in captivity if provided with the right conditions. They thrive in tanks with plenty of live rock and a sandy substrate, which allows them to exhibit their natural burrowing behavior. These gobies are not demanding when it comes to diet and will accept a variety of foods including frozen and live meaty foods, as well as high-quality marine pellets.

Reproduction

In the wild, Clitellate Gobies are known to form monogamous pairs and exhibit biparental care. While breeding in captivity is not common, providing a stress-free environment with plenty of hiding spaces can encourage natural reproductive behaviors.

Symbiosis

One of the most interesting aspects of the Clitellate Goby is its symbiotic relationship with certain shrimp species, particularly alpheid shrimps. In this mutualistic relationship, the shrimp digs and maintains a burrow that both the shrimp and the goby inhabit. The goby acts as a lookout, warning the shrimp of potential dangers with distinctive body movements. In return, the shrimp provides the goby with a safe haven and a place to lay its eggs.

Habitat

Callogobius clitellus is typically found in shallow, tropical marine environments, often in association with coral reefs and sandy bottoms. They are distributed across the Indo-Pacific region, from the Red Sea to Samoa, and from the Great Barrier Reef to Japan.
