Goldfish (details)

In the cold winter, how to make goldfish safely spend the winter has become a problem that breeders need to consider. Generally speaking, keeping goldfish just needs to remember the following simple matters.

If there is no old water at home before buying fish, raise goldfish with water that has been trapped for 7 days (that is, water with tap water in other utensils for more than 7 days).

Goldfish like to eat red worms, earthworms, shrimps, egg yolks and so on. In addition to artificial compound bait. It is necessary to ensure that the bait is fresh, and the spoilage can not be fed; Goldfish is a cold-blooded animal, so it is not afraid of cold. Generally can adapt to room temperature. As long as the water doesn't freeze, it's okay, but try to keep the water temperature constant. Hot and cold will definitely make fish catch a cold. Goldfish can be fed/kloc-0 times a day, but at a fixed time. Goldfish are greedy, and it is enough to feed them 80% at a time. If there is no filter, fish manure should be sucked out on time every day, and then the same amount of trapped water should be added and sucked out (trapped for 3 days), so that only a small amount of water can be changed to keep the water clean and oxygen can be injected. More than a week (or see water mixed), a lot of water change, that is, 1/3 water change is enough.

Before changing the water, put the trapped water next to the fish tank several hours in advance to ensure that the new water to be changed and the water in the fish tank keep the same temperature, so that the fish will not get excited.
