Carassius praecipuus is diagnosed from all other species of Carassius by having the origin of the anal fin located behind a vertical through the base of last dorsal-fin ray (vs. under dorsal-fi n base), 9-11½ branched dorsal-fin rays (vs. 11-21½), 25-27 +1 scales on lateral line (vs. 27-36 [total]), and 20-21 total gill rakers (vs. 23-128) (Ref. 116770).

Inhabits stream with 2-4 m width, about 30-50 cm depth, up to about 1 m depth in one of the curves, moderate current, and bottom consisted of gravel and pebble, with some areas cogvered by a thin layer of sediments. Occurs mainly in the deepest areas, under the roots of overhanging trees and bushes. Other fish species found were Opsarius pulchellus (Cyprinidae), Schistura coruscans, S. defectiva, S. personata, S. quaesita (Nemacheilidae), Oreoglanis sp.
