Variety of Fancy Goldfish · lionhead

📍 East Asia (China)

A fancy goldfish variety defined by its raspberry-like head growth (wen) covering the entire head and cheeks, paired with a rounded, dorsaless body and a split caudal fin. It is a slow swimmer that requires pristine water quality, benefits from a rounded tank or pond environment, and should be kept with other fancy goldfish of similar swimming ability.

Care Guide

Diet

Feed high-quality sinking pellets and flakes formulated for fancy goldfish once daily in small portions. Supplement with blanched vegetables (peas, zucchini) and occasional frozen foods like bloodworms or brine shrimp. Avoid overfeeding, which degrades water quality—only feed what can be consumed in 2-3 minutes.

Behavior

Lionheads are slow, methodical swimmers that spend much time foraging along the bottom and mid-water. They are peaceful and social, preferring the company of other fancy goldfish varieties. Their distinctive head growth (wen) requires careful observation for signs of infection or damage.

Breeding

Breeding in captivity is possible but requires significant space, cooler water temperatures (16-18°C), and conditioning with live foods. Spawning typically occurs in spring after a winter rest period. Fry are difficult to raise and require infusoria and microscopic foods initially; expect high mortality rates without dedicated breeding setup.
