Care
Green Clown Gobies are hardy and adaptable, suitable for both novice and experienced aquarists. They thrive in well-established aquariums with plenty of live rock for hiding and hunting microfauna. These gobies are small, reaching only about 1.5 inches in length, so they require minimal space. However, they should be kept in a tank with stable water conditions and a mature biological filter.
Reproduction
In the home aquarium, Eviota prasina may spawn if a pair is established. The male will guard the eggs, which are typically laid in a crevice or on the ceiling of a cave. Successful breeding in captivity is rare, but with careful attention to water quality and feeding, it is possible.
Habitat
Green Clown Gobies are found in the Western Pacific, from the Philippines to Australia. They inhabit coral reefs, often seen perching on branching corals or hiding in crevices. Their small size allows them to navigate the complex structures of the reef with ease.
