Betta miniopinna

Unknown

Overview

Betta miniopinna is a species of gourami endemic to Bintan Island in the Riau Archipelago of Indonesia. The species reaches 2.4 cm in standard length and is believed to be a facultative air-breather.

Betta miniopinna faces severe threats from peat swamp forest destruction across its limited range in Peninsular Malaysia. The species' specialized habitat requirements make it extremely vulnerable to logging, agricultural conversion, and peat extraction activities that have dramatically reduced suitable breeding environments. Water pollution from palm oil plantations and urban development further degrades the acidic, tannin-rich waters this species depends on for survival.

Threat summary

Habitat

Betta miniopinna inhabits shallow, slow-moving acidic waters within peat swamp forests of Peninsular Malaysia. The species requires heavily vegetated areas with dense aquatic plants and fallen logs, thriving in the dark, tannin-stained waters characteristic of pristine peat swamp ecosystems.
