Acanthocobitis zonalterans -In natural streamFound in a variety of streams from river mainstreams to small brooks. Seems to avoid mountain streams with steep gradient. Seems to prefer shallow riffles over small pebbles above which its maturated color pattern makes it inconspicuous from the surface. Also collected on a muddy to sandy substrate with a few stones/pebbles.
