Common name: Doublebar goby
General information
The Two-stripe Eviota, scientifically known as Eviota bifasciata, is a diminutive and charming species of goby that is well-suited for nano and pico reef aquariums due to its small size. These gobies are known for their peaceful demeanor and intricate behaviors, making them a fascinating addition to any small marine setup.
Characterized by their vibrant coloration, typically a translucent body with two distinct horizontal stripes, they are visually appealing and can add a pop of color to the aquarium. Their small stature, however, means they can be easily outcompeted for food and space by larger, more aggressive tank mates.

Care
Two-stripe Eviota gobies thrive in well-established aquariums with plenty of live rock and hiding places. They are not demanding in terms of care but do require stable water conditions and a varied diet of small, meaty foods such as copepods, brine shrimp, and finely chopped seafood. Due to their small mouths, food size should be considered to ensure proper feeding.
These gobies are not known to be aggressive and can be kept with other peaceful fish and invertebrates. However, care should be taken to avoid housing them with predatory species that may see them as prey.
Reproduction
Eviota gobies are known to have a short lifespan, and as such, they reproduce frequently. They are egg-layers, with the female depositing eggs in a secure location, often within the live rock or coral crevices. The male then guards the eggs until they hatch. In the aquarium, breeding may occur, but raising the larvae can be challenging due to their minute size and specific dietary requirements.
Habitat
In the wild, Eviota bifasciata is typically found in shallow, coral-rich environments and reef slopes. They prefer areas with abundant coral and rock formations that provide shelter and foraging grounds. Their natural distribution includes the Western Pacific, with sightings in areas such as the Great Barrier Reef, Indonesia, and the Philippines.
