Species overview
Siniperca undulata is a Percichthyidae from 中国. A thinking fish that rearranges décor and learns its keeper — and punishes bare, crowded tanks. It lives on the bottom. Adults reach 11.2–16.5 cm. A pair claims a territory; give each a defensible cave. Over-filter for its messy habits, aquascape with rock walls, and respect its claimed corner. Maintain 4–22 °C at pH 7–7.4. Best suited to a keeper who can match its natural water.
