Brachygobius Xanthozona Goby

Brachygobius xanthozona is closely related to other Bumblebee Goby species but is distinguished by its proportionally wider yellow transverse bands that give a bolder and higher-contrast banding pattern. Originally described from Borneo, it is found in brackish estuaries, tidal creeks, and coastal river mouths across parts of Borneo and the surrounding Indonesian archipelago. Like its congeners, it is a tiny goby rarely exceeding 4.5 cm that inhabits shallow, vegetated brackish-water environments. In the aquarium it requires the same specialised conditions as other Brachygobius: slightly brackish water with added marine salt, hard and alkaline water chemistry, small caves for territorial shelter, and a diet primarily of live or frozen micro-prey. It is more difficult to feed than many aquarium fish and is best kept in a species-specific setup or alongside other small brackish nano species. A rewarding fish for aquarists prepared to meet its dietary requirements.
