One of the difficulties and shortcomings of many people raise aquarium fish is the unusual and unexplained death of the aquarium fish. This has caused a lot of influence on the ecology of the aquarium and the psychology of farmers. So, why do aquarium fish die? Some of the sharing below will help you better understand this problem and take measures to fix it soon.

Eating problems of fish

In fact, most fish have a common habit of catching bait. Fish often do not distinguish whether they are full or not to stop like humans. Therefore, when stocking food in a tank, many people find that their finfish makes them think that they are hungry and feed a lot of food.

This does not only cause excess food in the tank to affect the water environment. If the fish is too full, they will get full stomach and die. This is one of the main reasons explaining why the aquarium fish die.

Oxygen problem in water

In order to survive, your aquarium water needs to provide enough dissolved oxygen for your fish. The bigger the number of fish in the tank, the higher the amount of oxygen needed. This is one of the very important issues that you need to be aware of. Because fish are like humans, oxygen exchange is required to survive.

However, lack or excess of oxygen is the cause of why the ornamental fish die, specifically as follows:

If the dissolved oxygen in the water is insufficient, the fish will not be able to conduct breathing normally. Since then, the fish in the tank will easily die. Conversely, if the tank is invested with aeration or filter production capacity is too large, exceeding the necessary threshold of the fish. This will also cause the fish in your tank to get tired and eventually die. Therefore, if your aquarium is small, use filters that are suitable for mini aquariums.

Water Environment

The source of aquarium water needs to ensure there is no chlorine in it. Because ornamental fish cannot survive in chlorine water.

Besides, people raise aquarium fish also need to pay attention that the temperature of the water, the pH level, the hardness of water are suitable for the fish so that they can grow and develop in the best conditions and do not die. This is also one of the reasons why aquariums die that you need to pay special attention to.

Lighting and temperature of the aquarium

Aquarium fishes also need to be provided with a suitable amount of light to grow. Besides, good lighting also helps the color of aquarium fish become more vibrant and beautiful. Therefore, if the amount of light in the tank is insufficient, not only will the aquarium space become dark, but the color of the fish will also become paler. At the same time, the ornamental fish will gradually die. Currently, players often use LED lamps for aquariums.

However, if the aquarium has too much light, it will cause the fish to become tired and gradually die.

Regarding the temperature, in the winter, the water in the tank is quite cold and if not rebalance in time will cause fish to die. The reason is that aquarium fish are mainly tropical fish, so they cannot stand cold water. Therefore, it is necessary to add a heater for the aquarium to promptly balance the water temperature in the tank.

Other causes

– Diseased fish: In the process of raising fish, you will find that your ornamental fish is very susceptible to diseases such as: Fungi, parasites on the body … These types of diseases can completely kill fish.

– Choose unsuitable fish species: If you choose to raise unsuitable fishes in the tank, it will lead to the situation that they often fight and cause damage and death.

– Quality of fish does not guarantee: If you accidentally buy the fish with weak vitality, in the process of raising them to die is absolutely possible. This is also the reason why aquarium fish die so commonly.

– Besides, some people are in a hurry so they often keep fish in new aquariums still with the smell of glue and chemicals that will make the fish easily die.
