The Goldfish (Carassius auratus) is a common and popular freshwater, and is most often seen in ornamental ponds and aquarium tanks. Goldfish are called cyprinids. Carp and minnow are also cyprinids.

Goldfish vary greatly in size, shape, and colour, but are usually white, yellow, orange, red, brown, and black.

Goldfish are typically about 5-38 centimetres (2-15 inches) long

In the wild, Goldfish feed on small sea animals, insects, and water plants.

Female Goldfish lay small eggs that stick to water plants. The eggs hatch within 4-6 days. Young goldfish are called fry.
