種の概要

Gobiidae species Rhinogobius rubromaculatus comes from mountain streams of E & S China. A benthic percher that spends its days darting between rock, glass and cave — structure decides its temperament. It lives on the bottom. Adults reach 2.5–3.7 cm. A bonded pair claims one cave; keep others elsewhere. Caves, stable pairs and clean sand keep this fish far calmer than open, bare tanks ever will. Maintain 18–26 °C at pH 6.5–7.5. A rewarding species for the aquarist who reads before buying.
