Care

Watchman Gobies are relatively easy to care for, making them suitable for both novice and experienced aquarists. They prefer a tank with a sandy substrate that allows them to burrow and create shelters. These gobies are peaceful and can be kept with a variety of other non-aggressive fish and invertebrates.

Reproduction

In the aquarium, Watchman Gobies may form monogamous pairs and spawn within the safety of their burrows. The male typically guards the eggs until they hatch.

Symbiosis

One of the most fascinating aspects of the Watchman Goby is its symbiotic relationship with pistol shrimp of the genus Alpheus. The shrimp maintains the burrow while the goby keeps watch for danger. This partnership is a remarkable example of mutualism, where both species benefit from each other's presence.

Habitat

Cryptocentrus strigilliceps is found in the Indo-Pacific region, inhabiting shallow lagoons and reef slopes with sandy substrates. They are often observed in pairs or small groups near their burrows, which they share with their shrimp partners.
