Care
Trimma Gobies are relatively easy to care for, but their small size means they can be outcompeted for food in larger aquariums. They thrive in well-established tanks with plenty of live rock for hiding and foraging. A varied diet of small, meaty foods such as copepods, brine shrimp, and finely chopped seafood is essential for their well-being.
Reproduction
In the aquarium, Trimma Gobies may spawn if they are kept in a peaceful environment with plenty of hiding spaces. The males guard the eggs, which are typically laid in a cave or on the ceiling of an overhang. Breeding these gobies in captivity can be a rewarding experience for dedicated hobbyists.
Habitat
Trimma Gobies are found in the Western Pacific, where they inhabit coral reefs and rubble slopes. They are often observed hovering close to the substrate or perched on coral branches, darting back to safety when threatened. These gobies prefer areas with moderate to strong currents and are usually found at depths ranging from 5 to 40 meters.
