Description

The scissortail rasbora is a cyprinid from Southeast Asia, from the Mekong and Chao Phraya, the Malay Peninsula, Sumatra and Borneo, and is kept worldwide in the aquarium trade. The species grows to about 13 cm and has an elongate, silvery body with a narrow dark midline; the deeply forked tail bears a black-and-white marking on each lobe that recalls a pair of scissors when swimming. It lives in schools in clear fresh water and feeds on insects, worms and small crustaceans. The eggs are hidden under bottom objects. The IUCN assesses the species as Least Concern (LC).
