The egg-fish goldfish is a fancy goldfish breed which lacks a dorsal fin and has a pronounced "egg"-shaped body. The egg-fish breed resembles the ranchu, but lacks the "hood" (or wen) typical of that goldfish; ranchu also tend to have shorter, squatter bodies.[1][2]
The phoenix is a Chinese goldfish variety with an egg-shaped body, a long tail, and lacking both a dorsal fin and headgrowth. It comes in all shades, colors and scale types.[5]
