The saramugo is a reophile species – it lives in river stretches with moderate to strong currents – and occurs preferentially below 350 meters above sea level, in narrow (< 20m) and shallow (< 60cm) watercourses with coarse substrate (e.g. gravel, rocks) and aquatic vegetation (immersed and along the river margins).
It prefers oxygenated water (> 9mg/L) of low to moderate currents (0,0-0,6 m/s) with temperatures varying between the 8,5 and 18 ºC, with some exceptions.
Saramugos diet is based on small invertebrates that exist in the water column and near the substrate, plants, algae and debris.
