Instructions for raising ornamental fish without dying

Today, ornamental fish have been and are explored by many people from urban to rural areas, from the elderly to young children. However, not everyone has the knowledge to care for fish as well as the correct breeding technique. This leads to fish being purchased after a period of time showing signs of disease, stunted growth and even mass death.

There are many people who come to see them and complain that “my family raises fish once in a while, then the fish are weak and then they all die together”. Because fish don’t live long, many people feel a lack of motivation to keep aquaponics going. There are even people who give up fish farming when before they were very “bubbling” with willpower. Our article below will help you gain experience in breeding and proper maintenance of ornamental fish.

Why do ornamental fish often die?

Feeding ornamental fish

In fact, baiting is the main set common to most aquarium fish. And the fish do not know how to distinguish if they are full to know the stop like us. Many times when we drop food in the tank and see the fish break, we think the fish is hungry and give it plenty of food. However, this is not true. It only affects the fish habitat by the amount of excess and stagnation of food. The worst consequence is that the fish is too full and then dies with a full stomach. This is one of the main reasons why aquarium fish don’t live long.

Reservoir aquatic environment

According to, the source of live aquarium fish should be clean and not contain any of the harmful substances such as chlorine. This is the environment in which aquarium fish do not survive and grow. Aquarium fish in particular should also pay attention to the water temperature in the aquarium. In fact, the most suitable temperature for aquariums is between 25 and 28 degrees.

A few fish can also live at 30 degrees, but this will definitely affect fish over time. Fish will be able to weaken, destroy the immune system and develop intestinal diseases in fish. Even fish don’t have a “lifespan”. Just keep cleaning the tank and changing the water every day but not ensuring the right temperature, the fish still struggle to live long. How to breed small aquarium fish is not difficult, it is important that you are really passionate and want to know more about it or not.

Another factor to consider is the pH of the water. Fish generally live in water with a pH between 6 and 8. But each different type of aquarium fish will grow stably in each different pH. Aquarists must naturally adjust the pH, limiting dependence on artificial products on the market. This helps ensure the longevity and stability of aquarium fish farming.

Oxygen in water

Your aquarium water must provide enough dissolved oxygen for the fish to survive. The more fish there are, the more natural the demand for oxygen supply. This is also something you need to be careful of. Fish also need oxygen for gas exchange to survive. However, the level of oxygen supply is also very important. If there is not enough oxygen in the water, the fish will not be able to breathe properly. As a result, the fish will easily die. On the contrary, if there is an excess of oxygen, the fish will lose its strength and gradually die.

Tank light and temperature

Aquarium fish also need a sufficient amount of light to thrive. In addition, light also affects the color of fish. Can help them have more beautiful and vivid colors that attract more attention. So, if the amount of light in the tank is not enough, not only will the aquarium space become dark, but the color of the fish will also become paler. At the same time, aquarium fish will gradually die.

However, if the aquarium is over-lit, the fish will gradually tire and die. In terms of temperature, generally in the north of our country, there are two very distinct seasons, winter and summer. In summer, if you leave the aquarium outside for too long or absorb a lot of sunshine, it will make the water hot and the fish will die easily. On the contrary, in winter, the water in the tank is quite cold and if it is not rebalanced over time, the fish will die. The reason is that ornamental fish in our country are mostly tropical fish, so they cannot tolerate a cold water environment.

A few other reasons

By taking care of the fish, you will find that your ornamental fish are very susceptible to common diseases such as: white mycosis, intestinal disease, red fungal disease in fish… These diseases very easily cause the death of fish.

Another reason is that farmers choose unsuitable fish. If the fish in the tank don’t match, they can fight to the death.

Ultimately, this may be due to the poor quality of the fish. If you accidentally buy a fish with low vitality, it is quite possible that it will die during the breeding process. This is also the reason why aquarium fish die quite often. Especially when buying an aquarium, you should be careful to buy a tank that does not smell like new glue or chemicals. The fish will be “poisoned” by the chemical smell and lead to death.
