they need a pretty big tank, would want it as wide as the max size and 3 times as long.
Size: To 85 cm (Okada, 1960), although Nina Bogutskaya (personal commun., 2002) reported seeing captured specimens in Russia approaching 1.5 m total length. In the Amur River where the species is native and the Syr Dar’ya of Kazahkstan where it is introduced, males tend to be larger than females, with a higher dorsal fin, wider interorbital distance, and longer snout, postorbital distance, and upper jaw. Moreover, morphometrics vary with age (Dukravets and Machulin, 1978).
Habitat preference: Stagnant shallow ponds or swamps with mud substrate and aquatic vegetation; slow muddy streams (Okada, 1960). Also occurs in canals, reservoirs, lakes, and rivers (Dukravets and Machulin, 1978; Dukravets, 1992; Nina Bogutskaya, personal commun., 2002). This species is an obligate airbreather (Uchida, 1933). It appears to occupy waters, usually with vegetation, close to shore, and also feeds in schools (Nina Bogutskaya, personal commun., 2002).
