Ask the master to answer, is the newly bought goldfish sick?

It's sick, according to your description, it should be caused by bacteria and parasites in the water, and it has invaded the fish. If it is unlikely, it is recommended to change to salt water with a very small concentration. In order to play a sterilizing effect on the fish body.

You can also use the medicated bath method, prepare a basin of low-concentration salt water, and a tank of fresh water that has been sun-dried for a few days, soak the goldfish in the low-concentration salt water for 5 minutes, and then fish the goldfish into the new water.

It is important to note that the water temperature should be consistent, otherwise the goldfish will catch a cold.

In addition, in the future, more attention should be paid to water quality in fish farming.

Sick. It seems that it is a bacterial infection that causes loose scales and then a fungal infection that is not easy to treat. The more modest method is a large salt + baking soda medicated bath.

5 parts per 1,000 (by weight).

Large bodies of water (reduce density, improve water quality).

If your fish is in good health, you may be able to save it.

Is there any loss of scales?

If it's just a whitening scale, it's not a big problem, it's the fish oil and scales on the body that are wiped off by the fish net when catching fish, and the color will slowly recover after a period of rest, so you can put a little salt appropriately.

This little goldfish may be sick, it is best to take it to a nearby pet hospital to see, otherwise, it may die, my fish have also had before, and finally died!

If you are sick, put salt in it, pay special attention to the quality of the fish, and pick the quality of the fish, otherwise, you will die in 1-2 days.

The problem with your dead fish is the problem of cross-infection. Why buy a new goldfish and come back, the goldfish in your house will die, because the newly bought goldfish you bought did not deal with the problem of disinfection and adaptation to the environment. Generally, the newly bought fish, do not immediately put it with the fish at your house, because the newly bought fish will have some bacteria that your fish's own immunity cannot resist, if you immediately put it in your fish tank and keep it with your fish, the bacteria on the newly bought fish will immediately invade your fish, and your fish will die in a short time.

You'll ask!Then why is it that the fish bought will be fine if it doesn't die. There are many aquarists who don't understand this problem, because these bacteria are generated in the water where you buy fish, and the newly bought fish has adapted to the water in the fish store, and of course the fish's own immune system has also adapted to these bacteria, and these bacteria have no effect on these fish.

But if these bacteria are carried to another tank by the fish in the fish shop, if you don't handle it well, then these bacteria will attack the fish in the other tank, and these fish are not so lucky, because their immune system is not adapted to these new bacteria at all. Therefore, there will be conditions one after another, which will lead to the death of the fish. What we have to do is to disinfect the newly bought fish with potassium permanganate to kill some of the bacteria on the new fish, and then use a separate container to raise them for a week, this week is for the fish to adapt to the new environment and new bacteria.

You'll ask!How can there be bacteria? Of course, there are bacteria, and there are thousands of bacteria in our human body, of course, there are good bacteria and harmful bacteria, and there are good bacteria that will help our body work properly.

Bad bacteria can be blocked by my immune system. So there is no harm to us, we are sick because of our own immune system, which causes harmful bacteria to invade and cause us to get sick. Fish is no exception, and there are many bacteria in the water, both good and bad, and these bacteria all play their due role.

As long as you sterilize the newly bought fish and keep it alone for about a week, the fish adapts to your water, and the bacteria on the fish are the same as the fish in your fish tank, and they also adapt to the water at your home. I've said so much, and I don't know if you can understand it. I hope you understand.

Raising goldfish is very simple, the main thing is to be careful! Generally, 4 small goldfish are enough in a round tank with a diameter of 20 to 30, and a fish can be raised with half a Coke bottle. First of all, the water temperature of the water when the fish is put into the new tank for the first time should not be much different from the water temperature of the temporary goldfish, which is as simple as putting the temporary storage box or bag in the water for 10 minutes, and then pouring the goldfish into the water.

As long as you survive, it's easy to do, whether you feed it or not for the first few days. Don't feed it too much, don't always want to feed it.

Put some greenery in there. It can produce oxygen in water. Small goldfish are very difficult to raise.

2 reasons.

1. Water quality problems.

2. The problem of the fish's own state.

It is very important for new fish to enter the tank and be watered, and it should be a dead fish caused by a cold caused by a large temperature difference.

Goldfish should have been parasited.

Soak with potassium permanganate for 10 minutes to disinfect and sterilize.

Ground into powder with Sophora sophora and mix it with food, feed it for three days.

1. Goldfish common fish disease (water mold disease).
