The key problem of fish farming lies in intentions and persistence, don't be too anxious, pay attention to the normal management day after day, survival of the fittest, to the weak and to retain the strong is what we should do.
Some time ago, several batches of small native fish entered in succession, and from the day they entered the tank, they were in the process of continuous elimination, and in the end, the only ones left were the elites.
So, why do you have to knock out a batch? What are the circumstances that need to be eliminated?
Most of the small ornamental fish are not the same batch of fish, which inevitably causes a variety of cross-infections, and some problems are not quarantined once or twice, and the germs will disappear.
Secondly, small ornamental fish are not resistant to tossing, whether it is for water temperature or water quality, especially some native ornamental fish, the demand for oxygen is still higher, and there may be a serious lack of oxygen in the process of remote transportation, which hurts the gills or other internal organs, which can not be cured no matter what medicine is given.
Moreover, the small fish is too small, the observation may not be careful, not only the trouble to fish, in fact, the process is also very troublesome, even if it is isolated alone, the container is too small The water temperature and water quality are not guaranteed, many conditions are not easy to achieve, and the whole tank may hurt the innocent, besides, the probability of ** is also very slim.
After many conditions are discovered, they are already very serious, and they are redundant in how to **.
If there are a lot of small ornamental fish in a tank, some of them die in the tank, which is not good for the water quality and other ornamental fish.
The first is the lack of energy, shrinking the fins and tails, such small fish, often left alone, do not eat, and are unable to swim, do not have a good, relatively normal cruising posture, and the body is relatively thin.
The second point is that the rotten fins are rotten and the tail is rotten, the gill cover is open and red, and there are also the tail or red half of the body that is red, and gradually begins to festering or exploding the scales as a whole, and the gill cover is open and difficult to breathe, and the mortality rate is higher and faster.
The third point is serious emaciation, accompanied by shaking the head and tail, the body is uncertain, and you can't stabilize your body shape at all, as a fish, you can't control your movements in the water very well, and you have no energy, then, you can basically announce that the game is almost over.
The fourth point is that the stool is severe, the white stool is dragged and eaten, or the ** is red and swollen, accompanied by abdominal distension or local fried scales, which is already the late stage of enteritis, and it is basically impossible to save it.
Therefore, it is found that some of the above situations appear, as long as there is weakness, excessive emaciation, fried scale ascites, shaking head and tail, directly fished out and fed to other ornamental fish, the rest of the spirit is cheered up, alive and vigorous, even if the water quality and environment are almost harmless, such small fish will be raised, no need to anything, will not be forced on water quality, will not be picky about food, and the water temperature is also easy to suit...
All in all, we only need to feed and change the water normally, and ensure that they will not have any serious diseases.
I am an old fish farmer, please pay attention to more ornamental fish problems, thank you!
