Cyprinidae species Devario sondhii comes from South & Southeast Asia. A restless micropredator of the surface film, evolved for open, sunlit water. It uses the whole water column. Adults reach 8.1–11.9 cm. Groups of 6 minimum; bigger schools calm them. Generous swimming room, a big school and clean water cover nearly all of its care. Maintain 23–25 °C at pH 6.5–7.5.
