Distribution: Western Pacific: Philippines to the Solomon Islands and Vanuatu, south to the southern Great Barrier Reef; Palau in Micronesia.
Diet:
Feeds on small interstitial invertebrates by sifting mouthfuls of sand.
Its diet should include a variety of live and frozen vitamin-enriched
brine shrimp, mysis shrimp, live black worms, and prepared foods for
carnivores. Unfortunately, many die from starvation in captivity. Live
brine shrimp and black worms can be used to induce feeding in finicky
individuals. Once eating, try to vary the diet as much as possible.
Because the Twinspot goby have a large appetite, a populated refugium
attached to the main tank will help by providing constant food supply
in order for them to maintain their body mass. Feed twice a day.
Additional information: The
Twinspot goby is from the Western Pacific region where it is found in
lagoons on sand and coral rubble substrates at depth of 1 to 100 feet
where it continually sniff the sand looking for food. It occupy burrows
used for shelter and reproduction. Its head and body are white
splattered with orange markings. It is easily identified by its large
erect dorsal fins, distinctly marked by eyespots. When another fish
sees the eye spots, it is fooled into thinking that the Twinspot goby
is a much larger fish.
Its feeding behavior can be helpful for
the home aquarium as it will prevent the development of "dead spots" in
the substrate. They do best in pairs and usually do not live long if
they are separated.
The ideal aquarium should have live sand
as substrate, plenty of places to swim and live rock under which to
burrow and hide. Because the Twinspot goby have a large appetite for
small invertebrates, a populated refugium attached to the main tank
will help by providing constant food supply.
Water temperature should be at 72 to 78° F with a specific gravity of 1.020 to 1.025 and pH between 8.1 and 8.4.
