📖 Overview

A medium sized fish that prefers shallow waters of sluggish streams or ponds with inflow water. It usually hides between dense aquatic vegetation to avoid predation. Feeds mainly on small aquatic invertebrates, any sizable floating organic fragments and surface-drifting terrestrial insects. A common food fish. Threatened by degradation of habitat (construction of hydroelectric power caused drastic diel fluctuation of water level (release and refilling of water) thus preventing growth of aquatic vegetation). It can now be found only in several streams near its type locality and is diminishing progressively, unless measures are undertaken to rescue remaining populations and to restore their habitats
