Description
The Portuguese Arched-Mouth Nase is a peaceful, schooling cyprinid fish endemic to river basins in Portugal. It is characterized by its subterminal, arched mouth adapted for scraping algae from surfaces. This species requires cool, well-oxygenated water with good flow, mimicking its natural riverine habitat.
