In a survey of fish diversity in the Bhadra River (which joins the Tunga to form the Tungabhadra) it was recorded alongside numerous other species including Puntius chola, Balitora mysorensis, and Mystus armatus. Dry season water paramaters were temperature 69.8°F/21°C, pH 7.0, hardness ~ 2.5°. The substrate was composed of bedrock, boulders, cobbles, gravel, sand and leaf litter in descending order of abundance with a maximum depth of around...
