Common name: Barr's Pygmy Goby

General information

The Barr's Pygmy Goby, scientifically known as Trimma barralli, is a small and colorful species of goby that is a delightful addition to nano and small reef aquariums. This species is known for its vibrant coloration, typically displaying a combination of yellow, orange, and blue hues that can add a pop of color to any tank. They are peaceful fish that are well-suited for community tanks with other non-aggressive species.

Care

Barr's Pygmy Goby requires a well-established aquarium with plenty of live rock for hiding and foraging. They are adept at navigating through tight spaces and can often be seen perching on coral branches or rockwork. These gobies are carnivorous, feeding on small crustaceans and zooplankton in the wild, so a varied diet of meaty foods such as brine shrimp, copepods, and finely chopped seafood is essential for their health in captivity.

Reproduction

Like many gobies, Trimma barralli are known to spawn in captivity. They lay their eggs in small crevices or under overhangs in the rockwork, and the male typically guards the eggs until they hatch. The larvae are planktonic and can be challenging to rear due to their small size and specific dietary requirements.

Habitat

Trimma barralli is found in the Western Pacific, including the Philippines and Indonesia. They inhabit coral reefs and rubble slopes, usually at depths ranging from 20 to 70 meters. In the aquarium, they appreciate similar environments with plenty of live rock and a sandy substrate to mimic their natural habitat.
