Common name: Redface dwarfgoby

General information

Trimma benjamini, commonly known as Benjamin's Pygmy Goby, is a small and colorful fish that is a favorite among nano-reef enthusiasts. This species is known for its vibrant coloration, typically displaying a combination of red, orange, and yellow hues with iridescent blue lines running along its body. Despite its small size, it has a big personality and is an active swimmer.

Care

Benjamin's Pygmy Goby is well-suited for small to medium-sized aquariums due to its diminutive size. They thrive in well-established tanks with plenty of live rock for hiding and foraging. This species is peaceful and can be kept with other non-aggressive tank mates. They are not picky eaters and will accept a variety of foods, but a diet rich in small live or frozen foods like copepods and brine shrimp will help maintain their coloration and health.

Reproduction

In the wild, Trimma benjamini are known to spawn within caves or crevices, laying their eggs on the ceiling. In captivity, they may breed if the environment is stable and there are adequate hiding places. The male typically guards the eggs until they hatch.

Habitat

Trimma benjamini is found in the Western Pacific, from Indonesia to the Great Barrier Reef and Micronesia. They prefer reef slopes and lagoons, often seen at depths ranging from 5 to 40 meters. In the aquarium, replicating their natural environment with a variety of live rock formations and moderate water flow will help these gobies feel at home.
