Gobiidae species Gymnogobius urotaenia comes from Japan & Korea. A benthic percher that spends its days darting between rock, glass and cave — structure decides its temperament. It lives on the bottom. Adults reach 10.5–15.4 cm. Pairs or small groups with ample hiding spots. 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. Undemanding once its core needs are met.
