Species overview
Percichthyidae species Siniperca knerii comes from 中国. Territory is its whole worldview; rocks arranged as walls calm what open water cannot. It lives on the bottom. Adults reach 28–41 cm. A pair claims a territory; give each a defensible cave. Strong filtration, hardscape boundaries and a steady routine turn a brawler into a showpiece. Maintain 4–22 °C at pH 7–7.4. A solid choice for a well-planned community tank.
