Common name: Blotched Sand Goby
General information
The Rusty Goby, scientifically known as Fusigobius inframaculatus, is a small and peaceful fish that is well-suited for reef aquariums. Its body is elongated with a soft, rusty coloration and subtle markings, which can make it a charming addition to a community tank. This species is not as commonly found in the aquarium trade as some other gobies, but it is appreciated for its gentle demeanor and interesting behavior.

Care
Rusty Gobies are relatively easy to care for, but they do require a tank with a sandy substrate and plenty of live rock to provide hiding places and surfaces for algae growth, which is a part of their natural diet. They are known to be bottom dwellers and rarely venture far from the substrate. A varied diet that includes small meaty foods and high-quality prepared foods will help maintain their health and coloration.
Reproduction
Like many gobies, Fusigobius inframaculatus is known to form monogamous pairs and exhibit biparental care. They lay their eggs in a sheltered location, often within the live rock or coral rubble. Both parents guard the eggs until they hatch, which typically occurs after a few days to a week, depending on water conditions.
Habitat
The Rusty Goby is found in the Western Pacific, from the Great Barrier Reef to the islands of Micronesia. They inhabit coral reefs and lagoons, usually at depths ranging from 1 to 30 meters. They prefer areas with sandy bottoms and abundant coral cover, where they can find food and shelter.
