Common name: Melasma pygmy goby

General information

The Twilight Dwarfgoby, Eviota melasma, is a diminutive and colorful species of goby that is a charming addition to any nano or small reef aquarium. This species is part of the diverse and numerous genus Eviota, which is known for its tiny gobies, often not exceeding a couple of centimeters in length. The Twilight Dwarfgoby is distinguished by its dark body with contrasting light spots and a vibrant yellow-orange stripe running from the eye to the base of the caudal fin.

Care

Eviota melasma is a hardy species that thrives in well-established aquariums with plenty of live rock and hiding spaces. They are peaceful fish that do well in small groups or pairs. Due to their small size, they should not be kept with large or aggressive tank mates. They accept a variety of foods, but small, meaty foods are preferred to maintain their health and coloration.

Reproduction

Like many gobies, Eviota melasma may spawn in captivity if provided with the right conditions. They are known to lay their eggs in crevices or on the ceiling of small caves within the live rock, where the male will guard and tend to the eggs until they hatch.

Habitat

Twilight Dwarfgobies are found in the Western Pacific, typically in coral reef environments. They prefer shallow waters where they can be seen darting among coral branches and rubble, often at depths less than 25 meters.
