Care

Aurora Gobies are relatively hardy and can be a good choice for both novice and experienced hobbyists. They thrive in well-established aquariums with a sandy substrate and plenty of live rock for hiding. These gobies are known for jumping, so a tight-fitting lid is essential to prevent escape. They accept a variety of foods, including frozen and live meaty foods, and should be fed multiple times a day for best health.

Reproduction

In the aquarium, Amblyeleotris aurora may breed if kept in a pair and provided with the right conditions. They lay their eggs in a burrow, which are then guarded by the male until they hatch. Breeding these gobies can be a rewarding experience for the dedicated aquarist.

Symbiosis

One of the most fascinating aspects of the Aurora Goby is its symbiotic relationship with pistol shrimps, particularly 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 safety for both parties and is a remarkable example of interspecies cooperation.

Habitat

Amblyeleotris aurora is found in the Western Pacific, from the Philippines to Australia. They typically inhabit sandy areas near coral reefs, often sharing burrows with pistol shrimps. In the wild, they can be found at depths ranging from shallow waters to about 25 meters.
