Why do goldfish die so easily? How to prevent fish from dying in hot weather?

For fish farming, although some infectious fish diseases are relatively less common in hot weather, fish are still prone to death, whether they are edible fish or ornamental fish. So, how to prevent fish from dying in hot weather? Let's take a look!

Why do goldfish die so easily?

1. Not feeding properly: Many friends are very "concerned" about raising fish. They will feed some food whenever they pass by the fish tank, or feed the fish to make them grow faster. These operations are to promote the rhythm of changing fish. Under normal circumstances, if it is just a goldfish of average quality, there is no need to feed it so well. It is enough to feed it 1-2 times a day at a fixed time. Each time the feed is fed, the fish should finish it in about 20 minutes. The unfinished food should be removed and the feeding should be reduced next time. What fish fear most is not hunger, but eating one meal and then going hungry, or eating too much all the time. These are fatal hazards to goldfish.

2. Fish disease prevention is not done well: Although fish disease prevention is indispensable in the whole goldfish breeding process, as long as you raise fish, you have to pay attention to this aspect, but the most dangerous time is the first half month after the fish comes back, so if you want to buy fish and raise them, you must first maintain the water in the fish tank. After the fish arrives home, you must disinfect the fish before putting it in the fish tank to avoid bringing pathogens into the fish tank. If necessary, you can use 0.5% coarse salt in the fish tank, which can effectively prevent some fish diseases and reduce the fish's stress response to the new environment.

3. Poor water quality: Fish eat every day and produce excrement. These excrement are important factors that endanger water quality. Therefore, during the entire fish farming process, you must change the water in the fish tank and maintain the filtration system in time. Only when the water quality is good and stable will the fish avoid or reduce the occurrence of problems.

How to prevent fish from dying in hot weather

1. Keep the water fresh: In hot seasons, water quality has a great impact on fish. If the water is not changed in time, excessive amounts of harmful substances such as ammonia in the water can easily cause fish to become sick or even die. Therefore, we must keep the water fresh. For fish tanks with poor filtration, we can regularly add some probiotics to the tank to accelerate the degradation of organic matter in the water.

2. Reasonable feeding: This is the most important thing to note. When feeding fish, it is best to avoid feeding them during the highest temperature period of the day, but also try not to feed them at night. It is better to let the fish finish the last meal of the day before dark, otherwise the fish are prone to hypoxia at night. At the same time, it should be noted that for some good quality fish, the feeding amount may be larger at this stage, so you can mix some allicin or probiotics in the feed to protect the liver, promote digestion and detoxification, which is more beneficial to the health of the fish.

3. Reasonable operation: In hot weather, if it is necessary to transfer or change a large amount of water for fish, you must pay attention to the temperature difference of the water. If it is transported over a long distance, it must not be exposed to the sun. It is best to put it in the car and turn on the air conditioner. Otherwise, the packaged water will rise quickly, which is extremely harmful to the fish.

What to do if you don't have an oxygen pump for goldfish

The function of the oxygen pump is not to directly inject oxygen into the water, but to bring the water from the lower layer to the upper layer to contact the air as the bubbles rise, thus adding oxygen to the water.

So if you don't want to use an oxygen pump, you just need to fully integrate oxygen into the water, so the best way is to use running water. However, goldfish is a still water fish and is not suitable for growing in strong currents or running water. At this time, you can consider adopting an auxiliary ecological model, using a plant tank, controlling the temperature, and increasing the oxygen content in the water through its own photosynthesis, but you need to pay attention to the oxygen consumption time.
