Species overview
From the waters of 中国 comes Glyptothorax hainanensis, a member of the family Sisoridae. A whiskered bottom resident whose day begins when the lights go off. It lives on the bottom. Adults reach 25.5–37.4 cm. Keep bottom stock light — they share one floor. Feed sinking foods after lights-out, keep the sand soft, and never let nitrate climb unnoticed. Maintain 18–26 °C at pH 6.5–7.5. A solid choice for a well-planned community tank.
