It is a perch-like ray-finned fish that belongs to the family Gobiidae under the order Perciformes of the class Actinopterygii. In the wild, they can be found in Western Pacific Ocean, ranging from the Moluccas to the Solomon Islands, north to the Ryukyu Islands, south to the northern Great Barrier Reef, and to Palau in Micronesia.
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. With its elongated body and blunt snout, the Orange Stripe Prawn Goby is a very beautiful fish that has a white body color. Its head and body have seven narrow orange bars. Its first dorsal fin is tall and fanlike, bearing prominent pale-edged black spots and numerous smaller white spots.
The dorsal fin consists of 7 spines with 12 soft rays while the anal fin contains 1 spine and 12 soft rays. The caudal, or tail fin, is usually longer than the head. Its body is covered with cycloid scales. This goby is a carnivorous fish and its food mostly consists of mysid shrimps, brine shrimp, cyclops, daphnia and other small invertebrates. It grows up to 10 cm in length and its lifespan ranges from 5 to 8 years.
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.
