Species overview

Cichlidae species Pelvicachromis pulcher comes from 南美洲及菲律宾. Territory is its whole worldview; rocks arranged as walls calm what open water cannot. It lives on the bottom. Adults reach 8.2–12.1 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 24–25 °C at pH 5–8. Water quality and diet matter more than décor.
