Care

Signalfin Gobies are known for their peaceful demeanor and are best kept in aquariums with plenty of live rock and sand substrate to mimic their natural habitat. They are sand sifters, constantly searching for small invertebrates and organic matter to eat. This behavior can help keep the sand bed clean and aerated. They thrive in a stable environment with consistent water quality, and they should be fed a varied diet of meaty foods, such as brine shrimp, mysis shrimp, and finely chopped seafood.

Reproduction

In the aquarium, Signalfin Gobies may spawn if kept in a pair and provided with the right conditions. They lay their eggs in a secure location, often within the live rock or coral rubble. The male typically guards the eggs until they hatch. Breeding these gobies in captivity can be challenging but rewarding for experienced aquarists.

Habitat

Fusigobius signipinnis is found in the Indo-Pacific region, from the Red Sea to South Africa and east to the Line Islands. They inhabit coral reefs and lagoons, often seen hovering above the substrate or nestled within the crevices of live rock. They prefer areas with moderate water flow and access to hiding spots.
