Also known as Hillstream Loaches, these fish are adapted to living on rocks and boulders in fast flowing mountain streams. They prefer oxygen rich water (plenty of aeration) and strong water flow from power filters. They will not typically do well in a setup that uses CO2. They are useful as algae eaters in tropical and sub-tropical aquaria, but do need some protein in their diet. They live in 6.6pH - 7.5pH.
This is a scale-less species and will require special medications.
