Description
Glyptothorax macromaculatus is a Sisorid catfish native to the fast-flowing, highly oxygenated hillstreams of Southeast Asia. It features a unique adhesive apparatus on its chest, enabling it to cling to rocks in strong currents. Its mottled brown and yellow coloration provides excellent camouflage against rocky substrates.
