Borneo Sucker (Gastromyzon sp.)
A fascinating, flat-bodied loach adapted to fast-flowing, oxygen-rich streams, the Borneo Sucker clings to rocks and glass with its specialised fins. With its mottled brown and gold pattern and constant algae-grazing, it's both unusual and practical for high-flow, well-oxygenated tanks.
