What season is easy to feed goldfish?

Goldfish is cold-resistant, as long as the water does not freeze, it will be fine, and the temperature requirement is not very great.

So goldfish can be kept all year round, but there are several points to pay attention to in fish farming.

1: To disinfect the new tank, soak it in salt water or potassium permanganate solution for 20 minutes, and then add water.

2. Fresh water should be deposited for two days before being put into the tank, so that the harmful substances in the water will be reduced a lot. Generally speaking, tap water needs disinfection when it enters people's homes. The commonly used disinfection method in the world is to add "chlorine", but excess chlorine often remains in water. If the residual chlorine exceeds 0.02ppm, it will cause strong corrosion to the fish mucosa. If it exceeds 0. 1ppm, some sensitive fish (such as peacocks, traffic lights and other small fish) will die. More than 1.0ppm can basically kill all kinds of common ornamental fish. Therefore, it is absolutely impossible to raise fish directly with tap water.

Fish need sunshine as much as people. It is best to equip the fish tank with lights and turn them on at a fixed time every day.

Try not to let the sun shine directly on the fish tank, as it will grow green moss.

4. Changing water is very important. Generally, it is enough to change one-third of the water a week. Changing water can replenish the mineral content lost in water and reduce the content of nitrate and nitrite.

If the above points are done, there will be no problem in keeping goldfish.
