The basics:
The Lionhead Goldfish is variety of fancy goldfish which gets its name from the characteristic growth at the top of the head which encompasses the cheeks and the gills, giving the appearance of a lion's mane. In addition, the Lionhead does not have a dorsal fin. Goldfish belong to the Carp family (Cyprinidae), and are some of the most commonly kept aquarium and outdoor pond fish. Goldfish are a domesticated version of a less-colorful Carp (Carassius auratus) and were first domesticated in China more than a thousand years ago.

The Lionhead Goldfish has a rounded or egg-shaped appearance like most fancy varieties of goldfish. The dorsal fin is absent while the other fins are rounded at their tips. The caudal fin is divided, forked, and has a butterfly-like appearance. Red and yellow color varieties are found in this species.

4-5 inches

Goldfish are very social fish, and flourish in a community tank free of aggressive fish. The Lionhead is a peaceful fish and can be kept in groups of 4 or more. They are also suited to a community tank setup. Keeping them with agile fast swimming tank mates is avoided so that these fish do not lose out on their quota of food.

These fish require a minimum tank size of 36 inches. The recommended substrate is sand. The tank should not be heavily planted because these fish require plenty of room to move around, and they tend to feed on soft leaves. Using too many rocks, caves, etc. to decorate the tank is avoided because Lionheads are slow swimmers and have poor eyesight, which makes them prone to accidents.
