Lazy fish
The “lazy fish” is a “tailor-made” pet fish for lazy people. He does not need to be fed for a month, does not need to be changed. water for a month and does not need to be kept warm in winter. “Lazy fish” is a “mixture” of a variety of fish species such as goldfish, lithium brocade, golden crucian carp and plane crucian carp. It has the body color of the goldfish, the body shape of the koi and the vigor of the crucian carp. . Among them, the fish has an arched body, a strong and plump figure, an upturned tail, and a bright color. “Lazy Mermaid” has a lovely name, “Hejin”, which means harmony and richness. Integrating the hybrid advantages of goldfish, golden lithium, golden crucian carp, plane crucian carp and other fish species, the "lazy mermaid" is no longer spoiled. Anyone who has raisedfish knows that if you directly use tap water to raise koi, goldfish, tropical fish and other ornamental fish, the fish will turn over (die) one after another within a short time. . However, the “lazy fish” does not have high requirements for water quality. When changing water, simply add a little salt to tap water to precipitate chlorine. Even if the water is not changed for a month, the “lazy mermaid” is still very much alive. Since they are raised in tap water, there are microorganisms in the tap water, and the newborn "lazy mermaid" can "eat" for a month. Some citizens just started breeding fish and giving lots of food to the lazy mermaids. If it were a goldfish, it would break its belly, but the "lazy mermaid" still swims happily.
