How to prevent diseases in the process of ornamental fish culture?

Tropical fish is a kind of ornamental fish cultivated in our family, which can beautify the environment at home and make people happy, so the culture of tropical fish is increasing. However, if the culture is not good, it is more likely to cause disease in fish, so prevention is the most important in culture.

The specific defense measures against fish diseases are as follows: new fish species, proper feeding, refusal of toxic substances or predators to enter the aquarium, correct use of heating lamps, lighting aerators and filters, and keeping the water quality fresh and properly stocked. In addition, because the relationship between aquatic plants and freshwater ornamental fish is very close, the cultivation of aquatic plants must not be ignored when maintaining the ecological balance of freshwater aquariums.

No matter where the ornamental fish are from, they have to travel a long way to enter the market, so it takes a long time to recover their strength before buying. Therefore, except in the fish merchant's aquarium, we should first observe whether they have potential diseases. However, the fish purchased for the first time should be quarantined in the aquarium in the first few weeks, and after that, each time a new product is added, it should be isolated in another aquarium. It will take a few weeks to live with the original fish life. The fish nets used to move diseased fish need to go through disinfection procedures and should be washed with a special disinfectant before entering the aquarium again, otherwise the fish nets used in the water body where the disease exists will bring germs to other water bodies.

When the feed is put too much, it will lead to the unlimited growth of algae and pollute the water, so the amount should be appropriate. The principle of a small number of times should be adopted when feeding, feeding 2 to 3 times a day, each time the feeding amount, it is appropriate for the fish to eat up in a few minutes, each time the amount should be fixed, not too much, the fish will eat up the detritus in the box, which is conducive to keeping the water quality fresh. If the feed is not suitable or the variety is too single, it will cause insufficient vitamin intake of fish and reduce the disease resistance of fish, so different brands of feed should be replaced to ensure the various vitamins needed by fish and avoid anorexia.

Careful observation is the key first step of fish. Daily observation can directly detect fish diseases and take emergency measures in real time to maintain a good ecological environment. Check the fish count regularly and call the roll when feeding to see if there are any absentees. If the aquarium has mixed fish of other different water layers, there is no need to panic if some fish occasionally do not appear, such as nocturnal active fish seldom appear during the day, but if they disappear for 2 or 3 days, you need to find out the reason, dead, unable to get out of the rockery, and be eaten by big fish, or jump out of the aquarium; in any case, you must find the fish carcass, otherwise it will pollute the aquarium. Watch for belligerence or other anomalies, such as forcibly overbearing or stabbing with fins. In the event of such a situation, if the fish is not a cluster fish, it only needs to be isolated briefly and isolated in the corner of the aquarium with a small floating tank. However, some fish behave rudely because they are lonely and bored without similar companions, so before punishing them, they should find out the reasons to meet their needs and provide enough playmates.
