Little is known about the biology of the malamída. However, the diet of all cyprinids is highly varied and can include insects, crustaceans, molluscs and occasionally plant material (2) (3). It can also be assumed that this species, like other cyprinids, is toothless, instead possessing a pair of enlarged bones known as ‘pharyngeal teeth’ within the throat which assist with processing food (3).
The exact breeding season of the fish is not documented. However, it is known that after migrating to a suitable spawning ground (5), the female malamída subsequently lays eggs among the stones on the riverbed (2).
