Subfamily: Gobiinae
Order: Perciformes (perch-likes)
Class: Actinopterygii (ray-finned fishes)
Maximum length: 3 in.
Minimum tank size: 25 gallons. The aquarium should be well-established.
Hardiness: Easy to Medium
Aggressiveness: Peaceful. Should be kept with peaceful tankmates. May fight with Hector’s goby – Amblygobius hectori. Generally aggressive towards closely related species.
Reef Compatibility: Excellent
Diet: Omnivore. The Rainford’s Goby continuously searching among sand and rock for copepods, worms, and detritus. It feeds by taking a mouthful of sand and sifting it through its gill rakers. It’s diet should be supplement with various meaty and herbivorous food such as live and/or frozen brine shrimp, mysid shrimp and prepared food for herbivore, as well as filamentous algae. Feed 2 times a day depending on live food availability within the aquarium. A refugium to keep up levels of live foods seems to help lot in captivity. It can also be a good idea to increase pod production by planting some easily pruned macro algae in the tank as well.
Additional information:
First discovered in the Western Pacific in 1940 by Whitely, the Rainford’s Goby is found in found in sandy or muddy-bottomed habitats close to coastal reefs of the Western Pacific region (Philippines south, Rowley Shoals, Great Barrier Reef, Fiji) at depths of 10 to 50 feet.. Perfectly suited for the reef aquarium, this beautiful little fish has a green and grey-blue body with five blue-edged orange stripes stripes running the entire length of the body and five white spots along the bases of the dorsal fins. While many gobies spend most of their time in repose on the substrate or in holes and crevices in the rocks, the The Rainford’s Goby is very active and spend most of its time hovering in the water column.
The ideal aquarium will have a temperature of 72ºF to 81ºF (22ºC to 27ºC) with a specific gravity between 1.02 and 1.025 and a pH of 8.1 to 8.4. Plenty of live rock to graze and suitable hiding places and open areas to swim is a must. It really does best if kept in a tank with some filamentous algae (almost essential to keep most individuals). Startled or continually harassed Rainford’s Gobies are known to jump from the aquarium. Unless the tank is large, it is best to keep only one of this species in an aquarium. However, some say that best behavior is exhibited when five or more are kept together (if introduced together) while some say they will eventually fight (it usually occurs singly in the wild).
It is possible for the Rainford’s Goby to spawn successfully in an aquarium but rearing the fry can be difficult because they are very small.
