A. rainfordi is a long and well rounded fish. It has a green to gray base colour, layered on top with bright orange stripes running the length of the fish, with black and white spots on its back and dorsal fin.

Similar Species

Belonging to the same genus, A. hectori has a similar body shape and head morphology. However, A. hectori has a more distinct black and yellow pattern.

Maximum Size

Attains a maximum length of 2"


A. rainfordi has a peaceful disposition, ignoring all other species within the aquarium which do not bare a resemblance to its own self. However, it will not tolerate another individual of its own species, fighting consistently no matter what size aquaria. They do not co-exist in the wild unless breeding. Will continually sift sand for micro-organisms, including polychaetes and other invertebrates.

Captive Care

75 litres (20 gal), with established sand bed and does best with hair algae for constant food supplementation.

Water Flow

Typical water flow for a reef aquarium (minimum 25 - 30x total tank volume turnover per hour)


No special lighting requirements. Enough to sustain a population of micro/hair algae.


Difficult to sustain in a home aquaria and should not be kept by amature aquarist's and requires special care in feeding. Will continually sift sand for micro-organisms, including polychaetes and other invertebrates. It is therefore necessary to have a mature tank with a sandbed full of organisms to supplement its diet.




Incompatible with members of it's own genus, Amblygobius, and boisterous fish which consume the same resources.


Compatible with all coral


Compatible with all other invertebrates.


Unknown in captivity.
