Similar Species

Crucian Carp differ from Goldfish in having a convex margin on the outer edge of the dorsal fin, vs. a straight to concave margin in Goldfish. Crucian Carp also have smaller scales, fewer gill rakers, a deeper body, a smaller eye, a different shape to the head and mouth shape, differences in the serration size and number on the dorsal and anal fin spines, and in body colour. Juveniles (to about 120 mm LCF) also have a distinctive blotch on the caudal peduncle just before the caudal fin.
