Eviota albolineata, the white-line dwarfgoby, was described by Jewett and Lachner in 1983. It is a small benthic goby reaching a maximum total length of about 3.6 cm. The species is restricted to the central Pacific and is reef-associated.

Taxonomy

• Family: Gobiidae
• Genus: Eviota
• Scientific name: Eviota albolineata Jewett & Lachner, 1983
• Common name: White-line dwarfgoby

Habitat

According to FishBase, the species is restricted to the Society Islands, Line Islands and the Tuamotu Archipelago. It occupies shallow lagoon and channel reefs, typically in water less than 3 m deep. Wikipedia notes that records reported from outside this range are likely misidentifications of the similar Eviota guttata.

Tank requirements

• Minimum tank volume: 50 L (13 gal)
• Temperature: 24-26 °C (75-79 °F)
• pH: 8.1-8.4
• Carbonate hardness: 8-12 °dGH
• Maximum size: about 3.6 cm total length (FishBase)
• Lifespan: 3-6 years

Diet

FishBase reports a trophic level of about 3.1, consistent with a micro-carnivorous to omnivorous diet of small invertebrates. In aquaria the species takes small frozen and prepared foods.

Compatibility

This is a peaceful, bottom-dwelling species. Because of its very small size it should be kept only with small, calm tankmates and away from larger predatory fishes.

Conservation status

IUCN Red List: Least Concern (assessed 2020).
