From the waters of Yangtze basin, China comes Parabotia bimaculata, a member of the family Cobitidae. A sand-sifting bottom resident most active after the lights fade. It lives on the bottom. Adults reach 11.9–17.4 cm. Gregarious bottom fish; 5 or more recommended. 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 solid choice for a well-planned community tank.
