Common name: Yellow-prawn goby

General information

The Yellow Watchman Goby, Cryptocentrus cinctus, is a small, peaceful fish that is a favorite among reef aquarium enthusiasts. Known for its bright yellow coloration and interesting behavior, this goby is not only attractive but also serves as a watchful guardian for its territory. It is often seen perched on rocks or substrate, observing its surroundings with keen eyes.

Care

Yellow Watchman Gobies are hardy and suitable for most reef aquariums. They prefer a tank with plenty of live rock and a sandy substrate where they can dig burrows. These gobies are known to form symbiotic relationships with pistol shrimps, so providing an environment that supports both can lead to fascinating interactions. They are omnivores and will accept a variety of foods including frozen and live brine shrimp, mysis shrimp, and prepared foods for marine fish.

Reproduction

In the aquarium, Yellow Watchman Gobies may form monogamous pairs and spawn within the safety of their burrows. The male typically guards the eggs until they hatch. Breeding these gobies in captivity can be a rewarding experience for advanced hobbyists.

Symbiosis

One of the most interesting aspects of the Yellow Watchman Goby is its symbiotic relationship with certain species of pistol shrimp, such as Alpheus bellulus. The shrimp maintains and digs the burrow while the goby stands guard against potential threats. This partnership allows both species to thrive, with the shrimp gaining a lookout and the goby a well-maintained home.

Habitat

Cryptocentrus cinctus is found in the Western Pacific, from the Philippines to Australia. They inhabit shallow lagoons and coral reefs, often associating with rubble and sandy bottoms where they can easily create burrows.
