Common name: Greybearded pygmy goby

General information

The Redhead Pygmy Goby, scientifically known as Trimma annosum, is a small and colorful fish that is a delightful addition to nano and pico reef aquariums. Its vibrant red head and contrasting body make it a standout species. This goby is part of the Gobiidae family, which is known for its diversity and adaptability.

Care

Trimma annosum is a hardy species that thrives in well-established aquariums with stable water conditions. They prefer tanks with plenty of live rock and hiding places to mimic their natural habitat. Due to their small size, they are best kept in smaller aquariums where they can be easily observed and fed. A varied diet of small live and frozen foods like copepods and brine shrimp will keep them healthy and colorful.

Reproduction

Like many gobies, Trimma annosum is known to spawn in captivity. They lay their eggs in small crevices or under overhangs in the live rock. The male guards the eggs until they hatch. Breeding them in a home aquarium requires attention to detail, particularly in maintaining water quality and providing the right food for the larvae.

Habitat

Trimma annosum is found in the Western Pacific, from the Philippines to northern Australia. They inhabit coral reefs and rubble slopes, typically at depths ranging from 5 to 40 meters. In the wild, they are often observed hovering near their preferred hiding spots, darting back to safety when threatened.
