Common name: Red-spotted pygmy-goby

General information

The Large-eyed Pygmy Goby, scientifically known as Trimma macrophthalmum, is a diminutive and captivating species popular among nano-reef enthusiasts. This species is part of the Gobiidae family, which is known for its diversity and adaptability. The Large-eyed Pygmy Goby is particularly noted for its large eyes relative to its body size, which is a characteristic feature of the genus Trimma.

Care

Due to their small size, Large-eyed Pygmy Gobies are well-suited for nano or pico reefs. They thrive in well-established aquariums with plenty of live rock for hiding and foraging. These gobies are peaceful and can be kept with other non-aggressive tank mates. They primarily feed on small crustaceans and should be offered a variety of live and frozen foods such as copepods and brine shrimp to maintain a balanced diet.

Reproduction

Like many gobies, Trimma macrophthalmum is known to spawn in captivity. They are cave spawners, laying their eggs in small crevices or under overhangs within the live rock. The male typically guards the eggs until they hatch. Breeding these gobies in a home aquarium can be challenging but rewarding for dedicated hobbyists.

Habitat

Trimma macrophthalmum is found in the Western Pacific, inhabiting coral reefs and slopes. They prefer areas with moderate to strong currents and are often observed in small groups or pairs. In the wild, they can be found at depths ranging from shallow waters to over 40 meters, showcasing their adaptability to different reef environments.
