Description

The mottled loach is a small stone loach (Nemacheilidae) from South and Southeast Asia. The species reaches about 15 cm and has an elongate, brown mottled body with dark cross-bars and, often, an eye-spot at the tail base. Around the mouth it bears barbels with which it probes the bottom. It inhabits clear, swift-flowing water of streams with a rocky, pebbly or sandy bottom. The diet consists of small bottom invertebrates, insect larvae and aufwuchs. Owing to its small size the species has no fishery value, but it is sometimes kept in the aquarium.
