Care

Sungam's Goby requires a well-established aquarium with a sandy substrate to mimic its natural habitat. It is essential to provide plenty of hiding places and a burrow, which it will share with its symbiotic shrimp partner. The aquarium should be equipped with a tight-fitting lid, as gobies are known to jump when startled. They thrive on a varied diet of meaty foods, including frozen mysis shrimp, brine shrimp, and finely chopped seafood.

Reproduction

In the aquarium, breeding Sungam's Goby can be a rewarding experience. They are cave spawners, laying their eggs in the safety of the burrow they share with their shrimp partner. The male is responsible for guarding the eggs until they hatch. Successful breeding requires stable water conditions and a stress-free environment.

Symbiosis

One of the most fascinating aspects of Sungam's Goby is its symbiotic relationship with pistol shrimps, particularly the genus Alpheus. This mutualistic association is a classic example of interspecies cooperation. The shrimp maintains and digs the burrow, while the goby serves as a lookout for potential threats. Their partnership is a remarkable display of communication and collaboration, with the goby signaling danger through body movements.

Habitat

Amblyeleotris sungami is native to the Western Pacific, where it inhabits sandy bottoms near coral reefs. They are typically found at depths ranging from shallow waters to about 25 meters. In the wild, they are often observed peeking out of their burrows, always vigilant and ready to dart back to safety at the first sign of danger.
