物种概述

Percichthyidae species Siniperca roulei 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 28–41.1 cm. Singly, in pairs, or as a harem — never crowded. Strong filtration, hardscape boundaries and a steady routine turn a brawler into a showpiece. Maintain 4–22 °C at pH 7–7.4. Water quality and diet matter more than décor.
