From the waters of Yunnan, China comes Schistura nicholsi, a member of the family Nemacheilidae. A sand-sifting bottom resident most active after the lights fade. It lives on the bottom. Adults reach 9–13.2 cm. Sociable; keep 4–6 so night-time activity stays confident. Choose sand over gravel, feed after dusk, and keep ammonia at zero — loaches punish neglect visibly. Maintain 18–26 °C at pH 6.5–7.5. A rewarding species for the aquarist who reads before buying.
