The fish inhabits shallow sand flats and slopes in bays, lagoons, and on back reefs and reef slopes within 18–80 feet depth ranges. It is also found on sand or mixed sand and rubble bottoms. This goby and the alpheid shrimp form a symbiotic relationship or partnership during nesting and feeding.

General Care

The Orange Stripe Prawn Goby is easy to care for and is suitable for a new aquarium hobbyists due to its hardy nature. It requires a 30 gallon or larger aquarium with plenty of loose coral rubble, sufficient swimming room and a sand bottom for burrowing. The aquarium should be maintained at a moderate temperature ranging from 72 to 78ºF. The pH and specific gravity should range from 8.1 to 8.4 and 1.020 to 1.025, respectively. Ammonia and nitrites should be absolute zero, while nitrate should be below 10 ppm in the water of tank.

Ideally, you should maintain 420-400 ppm calcium levels, 1260-1350 ppm magnesium levels and 8-12 dKH alkalinities, which help to stable pH level in your tank water.


The Orange Stripe Prawn Goby is a hardy species and easy to care for. This fish does very well in a reef aquarium and it is considered very reef-safe. This goby can be kept with other small, friendly fish, but should never be kept with aggressive fish such as triggers and basses. It becomes aggressive towards other similar bottom-dwelling species. It also likes to live in with alpheus shrimps in aquariums.


It accepts meaty foods, which include fresh or frozen mysid shrimp; vitamin-enriched brine shrimp and finely chopped table shrimp. Feed should be supplied at least 2 times a day.

Regular water changes are the best way to control any abnormalities. Maintain a healthy diet, as well.
