Common name: Candycane pygmy goby

General information

Trimma cana, commonly known as the Cave Goby, is a small and colorful species of goby that is a popular choice for nano and pico reef aquariums due to its diminutive size and peaceful nature. These gobies are known for their vibrant coloration, typically exhibiting a bright yellow-orange body with iridescent blue lines running along the head and body, making them a visually striking addition to any reef tank.

Care

Cave Gobies are relatively easy to care for, but they do require a well-established aquarium with plenty of live rock and hiding places to feel secure. They are not aggressive and can be kept with other peaceful tank mates. A varied diet of small, meaty foods such as copepods, brine shrimp, and finely chopped seafood is essential for their health.

Reproduction

In the aquarium, Trimma cana may breed if kept in a pair or small group, and the environment is stable. They lay their eggs in small caves or crevices, and the male typically guards the eggs until they hatch. However, raising the fry can be challenging due to their small size and specific dietary requirements.

Habitat

Trimma cana is found in the Western Pacific, from the Philippines to northern Australia. They inhabit coral reefs and are often found in caves or under ledges at depths ranging from 5 to 40 meters. Their preference for sheltered environments should be replicated in the home aquarium to provide a sense of security and natural habitat.
