Description
Astroblepus dux is a fascinating mountain catfish native to the fast-flowing, highly oxygenated streams of the Andes in Ecuador. This species is characterized by its specialized suckermouth and streamlined body, enabling it to cling to rocks in strong currents. Keeping them requires an intermediate to advanced level of care, focusing on pristine, cool water and robust water movement.
