種の概要
Osphronemidae species Betta rutilans comes from Southeast Asia. A labyrinth breather that cruises the plant tops like a sailboat in still water. It patrols the upper water. Adults reach 4.5–6.6 cm. Singly or in pairs; every gourami wants its corner. Prioritise calm surface water and cover from above; this fish dislikes current and commotion equally. Maintain 24–28 °C at pH 6–8. A rewarding species for the aquarist who reads before buying.
