How does tropical fish raise in winter, what should notice in winter?

In winter, the first thing to keep tropical fish is to control the water temperature, which is the main cause of its death, usually between 20-30 degrees Celsius. Secondly, regular feeding should be carried out, according to its different types, we should choose the right feed for feeding. At the same time, attention should be paid to changing water, which can maintain water quality and improve dissolved oxygen in water. When you change the water, you need to clean the fish tank and drain the dirt from the bottom.

1. control the water temperature

The first thing to do when raising tropical fish is to control the water temperature. For most tropical fish, 20-30 ℃ is the most suitable. A few fish can tolerate the low temperature of about 16 ℃, but if it is lower, it will lead to death.In addition, the water temperature should not be too high, high temperature will not be conducive to its survival, and will accelerate the reproduction of fungi, increase the possibility of illness.

2. regular feeding

There are many kinds of tropical fish, different varieties of food needs are not the same, some like to eat meat, some like to eat vegetarian.However, it is possible to feed with fish food, usually two to three times a day, so as to meet its growth needs, insufficient feeding will develop into an old fish, not big.

3. pay attention to changing water

Fish farming usually mainly change water, tropical fish is the same.It should be noted that because it has certain requirements for water temperature, the temperature of new water should also be controlled, usually a little higher than that of old water.In addition, before changing water, we must dry it, in summer, we need to dry it for a day, and in other seasons, we need to dry it for a longer time, so that we can remove chlorine.

Fourth, clean the fish tank

The fish itself will have excrement, and some fish food may not be eaten, thus becoming residual bait, which will pollute the water quality, if not carefully cleaned, it is likely to affect the survival of the fish, so when changing the water, they will be sucked away from the bottom.Filters can also be used to filter out dirt and then decompose it by microorganisms.
