Rhinogobius zhoui is a Gobiidae from mountain streams of E & S China. Every rock overhang is real estate; give each fish a cave and the tank stays peaceful. It lives on the bottom. Adults reach 2.7–4 cm. A bonded pair claims one cave; keep others elsewhere. Provide fine sand or smooth gravel, a cave per fish, and gentle to moderate flow. Maintain 18–26 °C at pH 6.5–7.5. Water quality and diet matter more than décor.
