物种概述

Silurus asotus, a member of the family Siluridae, is native to China, Korea & Japan. Its barbels read the sand like fingers; coarse gravel slowly wears them down. It lives on the bottom. Adults reach 85.5–125.4 cm. Keep bottom stock light — they share one floor. Provide soft substrate, hiding tubes, and food that reaches the bottom before tankmates finish it. Maintain 21–26 °C at pH 6.5–7.5. Water quality and diet matter more than décor.
