What is my favorite goldfish?

My favorite goldfish species: Dragon and Phoenix (with a day pearl and a phoenix flavor), Gao Feng (with a phoenix flavor and a high head), Feng Dan and Wendie.

Because the tail of the phoenix-tailed goldfish is very big, it is easier to make beautiful fish look like beautiful women, so I like this classical and elegant goldfish. As for Wendie, the hot money overlooks the goldfish gracefully, which is elegant and charming.

Large fins, with or without dorsal fins; The gluteal fin has single fin and double fin; The caudal fin is divided into 3 or 4 leaves and hangs freely; There are many kinds of body colors.

origin

Goldfish originated in China, and now goldfish all over the world are directly or indirectly introduced from China. Goldfish like water with sufficient light, suitable temperature, rich dissolved oxygen, clear water quality and no toxic substances. Goldfish can't jump, just swim slowly in the water, rarely stop for a long time, and the clustering phenomenon is not obvious.

Goldfish is an omnivorous fish, and likes to eat animal food, as well as plant seeds, leaves, buds and organic particles of aquatic plants. After the female fish lays eggs, the male fish immediately excretes milky semen, which quickly spreads in the water and meets the eggs for fertilization. The life span of goldfish depends largely on people's breeding management technology and living environment, generally 5-6 years, and the longest can reach 10-20 years.
