Barbodes amarus, known as the pait locally, is a species of cyprinid fish endemic to Lake Lanao in Mindanao, the Philippines. This species can reach a length of 10.8 centimetres (4.3 in). It was first identified from specimens collected from Lake Lanao in 1910 and 1922, and specimens were still present as recently as a 1982 survey of the lake. More recent surveys have failed to find species, leading to fears that it may be extinct.
