Care

Trimma Gobies are relatively easy to care for but do have some specific requirements. They thrive in well-established aquariums with plenty of live rock for hiding and foraging. Due to their small size, they are best kept in nano or small-sized tanks where they are less likely to be outcompeted for food. They prefer a varied diet of small meaty foods such as copepods, brine shrimp, and other microfauna.

Reproduction

In the aquarium, Trimma unisquamis can display interesting breeding behaviors. They are cave spawners, laying their eggs in small crevices or under overhangs. The male typically guards the eggs until they hatch. Breeding these gobies in captivity can be a rewarding experience for advanced hobbyists.

Habitat

Trimma unisquamis is found in the Western Pacific, from Indonesia to the Great Barrier Reef. They inhabit coral reefs and rubble slopes, usually at depths ranging from 5 to 40 meters. In their natural habitat, they are often observed hovering close to the substrate or within the protective maze of coral branches.
