Why do fish in fish tanks always die?

With the improvement of our living conditions, many people begin to keep pets at home according to their hobbies. For people, the longest pets are cats and dogs, and some people like to keep goldfish.

However, in the process of raising fish, there will always be fish deaths, and it is always necessary to buy fry every once in a while to raise fish. This process is repeated every year, which makes us a little discouraged and disappointed.

Personally, I keep fish in the bathtub because fish will never live long for the following reasons:

First, the water quality is not good. Fish have very high requirements for water quality, especially as ornamental fish, but also as a noble fish. Many times, due to busy work, we forget to change fresh water for fish in time.

If you live in a poor water environment for a long time, fish will naturally get sick and die. Because the fish tank belongs to stagnant water, there is no fresh water supplement. After long-term pollution, fish naturally die.

In addition to not changing water for a long time, it is also possible that fish farmers are not professional enough. Directly using fresh tap water to raise fish will also lead to the death of fish.

Because tap water contains disinfectant powder, it is not conducive to the survival of fish; Generally speaking, tap water for fish farming needs to be kept in a natural state for one day before it can be used for fish farming in fish tanks.

Second, hypoxia death In the process of raising fish, fish are also very prone to hypoxia death. For those fish tanks that have no oxygen production function, the change of weather and the growth of aquatic plants in the fish tanks will lead to hypoxia in the water.

In this case, the fish will die collectively. If it is found that fresh water or oxygen in water is replenished in time, this situation can be alleviated and the number of fish deaths can be reduced.

Based on the above situation, it seems that fish will die if they are raised in a fish tank; On the one hand, the water quality was polluted, and on the other hand, the fish died because of lack of oxygen in the water.
