Goldfish have many unusual body forms with a variety of colors. Bulge-eyed and multiple tailed forms are commonly produced for aquariums, but normal body form is robust and laterally compressed. The natural color is olive-brown dorsally to bronze-gold laterally and yellowish-white ventrally. Black, gold, bronze, orange, red, pink, and white, or combinations of these colors are often found. Serrated spinous rays occur at the front of the dorsal and anal fins, which distinguishes goldfish from the native minnows. The complete lateral line has 25 to 30 scales. The dorsal fin, which is much longer than those of native minnows, has 15 to 19 soft rays, while the pectoral fins have 15 to 17 soft rays, and the pelvic fins usually have 9 soft rays.
