Overview
The Brahm's dwarfgoby is a peaceful little goby for a small reef tank, and an easy fish once it settles in.
Did you know
The Brahm's dwarfgoby entered the hobby directly as a captive-bred fish. It reached aquarium tanks through Biota's Palau hatchery within a decade of receiving its scientific name.
Caring for the Brahm's dwarfgoby
Give a Brahm's dwarfgoby a small tank of 5 gal (19 L) or more. Plenty of cover and gentle flow help a new fish settle in. With a pocket of slow water, it will hover just off the rock instead of sitting on it, which is unusual among dwarfgobies.
Keep the water at 72 to 79°F (22 to 26°C) with a pH of 8.1 to 8.4. Expect a shy first week or two, then regular appearances at a few favorite perches once it trusts the room. It eats small pellets, Calanus and other fine meaty foods.
The Brahm's dwarfgoby is peaceful and reef safe, and it is fine singly or in a small group. House it with nano-sized, mild tank mates rather than anything large enough to eat it. It is moderately hard to breed.
Good to know
Greenfield and Tornabene described the Brahm's dwarfgoby in 2014 from New Hanover. It is named for Brahm Kai Erdmann, who recognized that these fish had been passing under the name Eviota nigriventris in the scientific literature. A single red-orange stripe bordered in white runs along the body. Both sexes carry an elongated dorsal fin.
In the wild
The Brahm's dwarfgoby is known from reefs around Papua New Guinea, including New Hanover, New Ireland and New Britain. It lives from the surface down to about 20 meters.
