Neglected Shrimpgoby

Geographical Origin and Habitat: Amblyeleotris neglecta is distributed across the Western Pacific Ocean, from southern Japan to northern Australia. It is found on sandy flats, mudflats, and rubble areas near coral reefs, typically at depths of 5 to 25 meters.

Taxonomy and Morphology: Member of the Gobiidae family, genus Amblyeleotris. Features a slender, cylindrical body, a broad mouth, and large, closely set eyes located high on the head to scan for threats. It grows to a maximum length of about 9 cm.

Social Behavior: Peaceful and cautious species. It forms a symbiotic bond with alpheid snapping shrimps. The goby acts as the visual guard at the entrance of the shared burrow, signaling safety or danger to the shrimp through touch and tail vibrations.

Coloration and Sexual Dimorphism: Body base color is whitish or pale cream, decorated with narrow, vertical reddish-brown or orange bands. Iridescent blue and yellow speckles appear on the cheeks and dorsal fins. No visible sexual dimorphism is present.

Aquarium Setup: Minimum aquarium size of 90 liters. Requires a deep sand bed of fine grain (5-8 cm) to support burrow construction. Rocks must be resting directly on the bottom glass to prevent collapses from the shrimp's continuous excavation work.

Diet and Feeding: Carnivorous. In the aquarium, feed small frozen foods like mysis, brine shrimp, and copepods. Direct the food toward their burrow entrance using a pipette. Sinking marine pellets are also accepted once the fish is acclimated.

Water Quality: Keep standard marine parameters stable: temperature 22°C to 27°C, pH 8.1 to 8.4, and specific gravity 1.020 to 1.025. Good filtration and regular partial water changes are necessary to maintain low nitrate levels and high oxygenation.

Compatibility and Cohabitation: Peaceful and reef-safe. It is highly recommended to house it with a symbiotic Alpheus shrimp. Avoid housing with large, predatory, or aggressive bottom-dwellers that might outcompete it or pose a physical threat.

Aquarium Breeding: Captive breeding is undocumented in the hobby. While paired fish may lay eggs inside their burrows, raising the pelagic larvae is extremely difficult due to their microscopic size and complex dietary requirements.

Risks and Diseases: High risk of jumping out of open aquariums, requiring a tight lid. They are shy feeders and may starve if kept with fast, voracious open-water tankmates. Ensure they receive adequate food at the bottom of the tank.
