Species overview
Parosphromenus deissneri, a member of the family Osphronemidae, is native to Borneo & the Malay Peninsula. It gulps air at the surface, so warm, still, plant-covered water is home — and cold drafts are not. It patrols the upper water. Adults reach 2.8–4.1 cm. A pair bonds loosely; keep décor between rivals. Give it warm, gentle water, floating plants and quiet neighbours; filter flow should barely ripple the surface. Maintain 25–27 °C at pH 6–8. Best suited to a keeper who can match its natural water.
