Where can I find a detailed introduction to tropical fish disease prevention and control?

In the spring, the weather is warmer, and the ornamental fish after wintering begin to be active, but their physique is relatively weak, and the amount of bait should be gradually increased. Due to the large climate change, special attention should be paid to heat preservation when it is windy and rainy. Bacteria and viruses also multiply rapidly in spring, and fish diseases are most likely to be prevalent.

It is easy to hurt the body of the fish by pulling the net to catch fish, so we must pay attention to disease prevention and treatment.

In the long winter, tropical fish still grow and develop normally in a small number of families with particularly good fish breeding conditions, relatively sophisticated fish farming skills, and plenty of time to play, and the fish in ordinary families are much inferior to summer due to various reasons such as long-term ingestion of artificial bait and lack of light. In view of this, throughout the winter, especially when the days are getting longer and longer, the sun is getting more and more, the gonads of tropical fish are developing faster, and a lot of nutrients are needed, it is necessary to try to feed some fresh bait. The main ones of fresh bait are:

Small-scale cultivation on their own indoors; Look for ditches with a lot of organic matter or pits with domestic sewage entering the pond, and dig earthworms from the sediment; To the large-scale pit pond where there are more fish and insects, break the ice to catch the "green jump" fish, insects (scratch the foot), in Beijing and other big cities, you can also buy it in the bazaar.

After a winter of feeding, although the dirt in the aquarium is often removed and the water is partially changed, the bait and fish excrement will still accumulate more and more, and a "big cleaning" should be carried out, that is, the fish and aquatic plants are all taken out from the aquarium, and the old water in the upper layer of the box is stored in the bucket, and then thoroughly scrub the gravel at the bottom of the box, rinse it with clean water for later use, and carefully scrub the inner wall and bottom of the aquarium until it is clean.

Dust-free and odorless. After all these tasks are done, sand is laid, water is injected, grass is planted, and fish are added in turn, and the water is clear, the grass is green, and the fish is fresh. This kind of "big cleaning" should try to completely remove the dirt in the wall, bottom and gravel of the box to improve the water quality.

At the same time, don't change the water too much.

Control the temperature is generally fine, clean up the fish poop in the fish tank in time, change the water in time, and salt it from time to time to prevent it.

Control the water quality, this is more important than anything else, and then wash the filter frequently, basically there will be no problem. In addition, salt also has a certain effect, when you find that the fish rubs against the tank, you can put some appropriately and then change the water, but don't use salt as medicine. You can also use methyl blue as a prevent, 100 liters of water with 5 ml of water every other day.

In fact, fish don't like to get sick in winter, on the contrary, summer is the season of disease! As for how to prevent me from saying too one-sidedly here, I'll give you a Q group, and all the problems can be solved if you apply for it!

What are the common diseases of monk fish**.

My newly bought little red fish doesn't eat.

The fish is covered with black spots.

What did my little red fish die of?

Can you help me take a look.

This is a bacterial infection, a problem with the water, it may be that the water is rarely changed or the water is not sterilized normally under the sun or there is too much food, which causes the water quality to deteriorate; It should be disinfected with potassium permanganate.
