The Spotted Dwarfgoby, scientifically known as Eviota guttata, lives up to its name as a small fish species. Initially, it was considered to have the smallest vertebrae, although that distinction now belongs to either a frog or a smaller fish. It was first described in 1978 by Lachner, E.A. and S.J. Karnella from specimens found in Ethiopia.

These tiny fish lack swim bladders, which is not a problem since they spend most of their time on the substrate where buoyancy control is not critical. Although they don't possess a lateral line, they have sensory organs around their head.

The Spotted Dwarfgoby usually grows up to a maximum length of just over three cm. They have the typical goby-shaped body with an elongated cylindrical shape and two dorsal fins. Their body is light grey-white with scattered red blotches along the upper part of the body, while their nasal projections are proportionally large for their size.

Common in Tanzanian coastal waters, spotting these fish can be challenging due to their small size. They make quick darting movements on the reef, probably in pursuit of prey. When approached, they freeze in place, and if they feel threatened, they dart away in a series of rapid hops and seek shelter.

The Spotted Dwarfgoby likely feeds on small microorganisms found on the reef and is capable of making short, quick jumps to catch its prey.

While not commonly traded, there is no reason to believe they wouldn't thrive in a tank as long as there are no predators present. Given their small size, they would be vulnerable to predation by larger fish.
