The British Lionhead is closer to the flat-backed Chinese Lionhead than to the Ranchu, which has a dorsal contour that curves sharply down to the caudal peduncle. The hood is the dominant feature and the fish should have a nice lean back.
The colour may be metallic (self-coloured or variegated in a pleasing pattern and similar on each side) or calico. Metallic colours should appear as burnished metal, extending into the fins. Calico fish should have a blue background with patches of violet, red, orange, yellow and brown, spotted with black.
