Gymnocypris przewalskii is a Cyprinidae from 中国. Its home water is snowmelt: cool, fast and oxygen-saturated, with hot summers as the main threat. It uses the whole water column. Adults reach 11.2–16.5 cm. Young fish group; grown ones want space. Keep it cool, moving and oxygen-rich; summer temperatures above 24 °C are the real danger. Maintain 18–26 °C at pH 6.5–7.5. Undemanding once its core needs are met.
