Will goldfish stop swimming in cold weather?

Maybe. In autumn, when the weather gets cold, the activities of goldfish will slow down. At this time, it should be noted that sometimes the temperature is still high at noon, and the fish tank needs short-term shading. Goldfish often lie on the bottom of the tank in the morning and evening, and the water quality in the tank should be kept clean to avoid feces corroding fish scales. In autumn, goldfish have less activity, so they will eat less. However, the supply of fish and insects should make the fish tank surplus. At this time, in order to let the fish eat more feed, it is necessary to save your strength and prepare for the winter. Feeding can be stopped at the first frost. The indoor temperature is generally above 6 degrees, and the water temperature should be kept at 5 degrees. If it exceeds this temperature, you have to feed it. There is another possibility. The weather is sultry and there is no wind at night, and the floating head of goldfish usually begins in the middle of the night. If the goldfish swims in the water, it is scattered but not heavy, indicating that there is no oxygen in the water. If the fish sinks, it means that the floating head is light. If the gill cover of goldfish does not move, it will be in a state of shock. This shows that it is close to the pot, so it is necessary to rescue it in time, and the fish can be fished into the spare fish tank or basin.
