The Borneo Sucker (Gastromyzon borneensis), lives in fast flowing shallow streams and can be kept in an aquarium with a strong water flow.
Their natural habitat has lots of boulders that supply well oxygenated fast moving water over the rocks. These conditions are great for algae growth and the tiny invertebrates that live within the algae called aufwuch. Borneo suckers eat the Aufwuch.
Borneo suckers have adapted to cling on to rocks to stop them from being swept away. Their temperate natural climate allows them to be kept in coldwater aquariums and they are often added as cold water algae eaters. They are often kept in tropical tanks as well as coldwater aquariums.
They need a minimum tank size of 60cm and they prefer temperatures between 15-25 degrees centigrade. Provide the with neutral to slightly alkaline water conditions. There is little information known on the captive breeding of this fish.
