Care
Tomiyamichthys oni requires a well-established aquarium with plenty of live rock for hiding and hunting microfauna. They are generally peaceful and can be kept with other non-aggressive tank mates. It's important to have a tightly fitting lid as gobies are known to jump, especially when startled or in new environments.
A varied diet of meaty foods such as brine shrimp, mysis shrimp, and finely chopped seafood is essential for their health. They may also accept high-quality pellet and flake foods.
Reproduction
Oni Gobies are not commonly bred in captivity, but like many gobies, they are likely to form monogamous pairs and spawn within the safety of their hiding places. The male typically guards the eggs until they hatch.
Habitat
The natural habitat of the Oni Goby includes sandy bottoms and coral reefs where they can be found at various depths. They are indigenous to the Western Pacific, with sightings around Japan and the Philippines.
In the aquarium, they appreciate a sand substrate and areas of low flow where they can sift for food without strong currents.
