About
Formosania lacustre is a stout Taiwanese hillstream loach with a wide adhesive disc and a compact, heavily built body for withstanding powerful mountain torrents. Its care requirements overlap significantly with Crossostoma lacustre, which it shares habitat with in Taiwan's cooler montane river systems. In an appropriate setup it is an active and long-lived display fish for the dedicated hillstream hobbyist.
