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.
