Why do my tropical fish die of old age?

The death of tropical fish indicates a problem with water quality, oxygen and disease. Let's talk about how to raise tropical fish correctly.

Choose a fish tank and choose the size of the fish tank according to the number and size of the fish you raise. The small tank is below 60cm, and the large tank is mostly one meter and one meter two. Depending on the type of fish, the basic rule is that a smaller fish can have 1 liter of water and will not be too crowded.

Fish tanks are further divided into bare tanks and aquariums. If the material of the bare cylinder is optional, it is recommended to choose ultra-clear glass. Very translucent.

The aquarium is filtered and heated, and the cylinder head is all in place. It's more convenient. It is not recommended to choose those special types of fish tanks, such as those with arcs, which will make you dizzy after watching for a while.

Because there is a magnifying effect. After the fish tank is bought, try to put it in the shade to prevent direct sunlight, otherwise there will be a lot of green algae on the fish tank.

Install a heating rod and set the temperature at 28,9 degrees is more appropriate. Now most of the temperature of the heating rod cannot be reached, so it is appropriate to open it higher.

Install a filter, this is the key to fish farming. Filters include upper filtration, waterfall filtration, bottom filtration, and external filtration. If you have the ability to choose an external filter barrel as much as possible, the filtration is relatively clean. The filter media is relatively abundant. High playability.

Add decorations, as simple as putting some stones or washed sand. It is conducive to the cleaning of water quality in the future. Because these things are good for the growth of nitrifying bacteria. You can also put some sunken wood and aquatic plants, which is conducive to the hiding of timid fish, and can also breed small fish. Avoid being eaten.

When the water is stable, you can buy your favorite ornamental fish. In the order of entering the tank, first put the fish in the tank with the bag to let the fish adapt to the water temperature, and then put some water in the tank into the bag at appropriate intervals. Adaptation to water bodies.

About 3 times, you can fish into the tank. Remember not to pour the water you bought from outside into the tank, because most of the water outside has medicine.

In terms of daily management, it is fed twice a day, once at bed and once at dinner. It is best to let the fish eat in 30 seconds at a time. Change one-third to one-fourth of the water in the tank a week.

There are many reasons why tropical fish die, it can be because the temperature is too low, the water quality is too poor, or the fish are not sick in time**. If the temperature is too low and you need to pay attention to heat preservation at ordinary times, it is best to use a heating rod to continuously control the temperature, and the water temperature should be maintained above 20. If the water quality is too poor, the fish need to be changed regularly, usually once every three to five days.

If it is caused by a disease, it is necessary to observe regularly to see if there are any signs of illness, and if you get sick, you should take medication according to the condition.

1. Daily feeding: If you want to feed tropical fish, you must first ensure feeding. Usually feed neither too much nor too little.

Feeding too much will accelerate the deterioration of water quality, which is very bad for the health of the fish, and too little feeding will lead to nutrient deficiency. Usually feed three times a day, and each feeding should be eaten within 3-5 minutes.

2. Regular water change: In order to maintain water quality, it is necessary to change the water in the fish tank regularly, even if there is filtration equipment, the ammonia nitrogen in the water will still increase, so the water should be changed once a week, and each water change can be changed by one-fifth. When changing the water, you need to pump the water before you can pour the trapped new water into the tank.

3. Pay attention to the temperature: since it is a tropical fish, there are certain requirements for temperature, the minimum water temperature can not be lower than 20, for some large fish to Xiaozheng's said, the water temperature should be higher, at least 24 or 26 or above, and some even reach 28.
