General information

The Nebulous Dwarf Goby, Eviota nebulosa, is a small and colorful species of goby that is popular among nano-reef enthusiasts. This species is known for its diminutive size and vibrant coloration, which can add a pop of color and activity to a small reef aquarium. They are typically yellow to green in color with intricate, nebula-like blue to purple patterns on their body, which is where their name derives from.

Care

Eviota nebulosa is a hardy species that can thrive in a well-established aquarium with stable water conditions. They prefer aquariums with plenty of live rock and hiding places to feel secure. Due to their small size, they are best kept in nano or pico tanks where they are less likely to be outcompeted for food by larger tank mates. A varied diet of small, meaty foods such as copepods, brine shrimp, and finely chopped seafood is recommended for their well-being.

Reproduction

Like many gobies, Eviota nebulosa is known to spawn in captivity. They lay small clutches of eggs that are often attached to the substrate or aquarium glass. The male guards the eggs until they hatch. Breeding them in captivity can be a rewarding experience for the dedicated hobbyist, although raising the larvae can be challenging due to their minute size and specific dietary requirements.

Habitat

Nebulous Dwarf Gobies are found in the Western Pacific, from the Philippines to northern Australia. They inhabit coral reefs and rubble slopes, typically at depths ranging from 1 to 30 meters. In their natural habitat, they are often observed hovering near coral heads or rock outcroppings, darting back to safety when threatened.
