Description
Biota Blackbelly Dwarf Goby (Eviota atriventris)
Together with species of the genus Trimma, members of Eviota are sometimes referred to as pygmy gobies or dwarf gobies. Eviota spp. are quite tiny fish (the “iota” in their name suggests smallness, as they were the smallest known vertebrates when they were named); they are even small among their fellow gobies and are, in fact, still among the smallest fishes in the world. Of course, this helps to make dwarf gobies such as the blackbelly dwarf goby great candidates for a nano or even pico aquarium. In larger tanks, this species (unlike so many other gobioids, which tend towards intraspecific aggression) tolerate each others’ company and may form shoals when stocked in groups.
The blackbelly dwarf goby (especially when captive-bred) is quite easy to care for, as it adapts well to captive environments and readily accepts a wide variety of live and prepared aquarium foods.

Eviota sp. Goby Species Information
This species is distributed widely across the western Pacific Ocean from Japan to Thailand to Australia. Though it may live a solitary life, it frequently forms groups that share small territories near branching corals where they quickly retreat when approached by other, larger fish.
Benefits of Aquacultured Eviota Gobies
Aquacultured livestock are always preferable to wild-caught specimens. For example, when bred and raised captivity, they adjust much more easily to aquarium life. Furthermore, they also are less likely to carry disease. Aquacultured specimens can better tolerate shipping stress. By purchasing captive-bred gobies you support the aquaculture of marine organisms and help to make our hobby more sustainable!
