What is the reason why the pearl goldfish suddenly lost weight, its color was dark, and its appetite

You didn't use a heating rod, did you? It is recommended to buy one to control the temperature at 26-28 goldfish will reduce their activity according to the water temperature, and generally this is called a decrease in activity, which many fish will.

The water temperature is 26-28 1 is able to reduce the outbreak of fish diseases, for example, water mold white spot 2 is able to maintain a constant temperature, so that the fish will grow relatively faster, and there will be no problems that you have now, if the fish is sick, it will be directly manifested on the body of the fish, on the scales, on the head, etc.

Why do fish exercise less in the winter when the water temperature is relatively low?

It's because there is less food in the winter than in other seasons, so they reduce their activity to make sure they can survive the winter.

The reason why your fish are lean is because your water temperature is always low, and his appetite is always poor, and the smaller the water area (the less water), the greater the change in water temperature.

For example, if you put boiling water in a small cup, it will cool faster, for a reason.

1.It is necessary to observe the relationship between the fish in the fish tank, and the fish also have partners and mates like people, and it is necessary to find out the reason, maybe it is because of the relationship between one fish that drives the emotions of the fish in the whole tank.

2.It may be due to the hot weather, at this time, you should feed some small nematodes or mud bugs, and do not blindly feed only fish food.

3.Change the water frequently.

Kill the parasites first.

Trichlorfon splashes do not need to change the water.

Sterilize every other day.

Splash bleach powder 1ppm without changing the water.

Change the water by a third every other day.

Mix the crushed garlic in the feed and feed it.

You're the same as my goldfish, they're like that, and I don't know what's going on, I don't eat.

Let's raise it alone, quickly drop it, put some salt, and put it in after it's done, which means it's dying.

Either you don't fit in or you're going to die, try it alone in clear water.

Have you not bought an oxygen pump, generally this is a lack of oxygen, and you have to wash the fish tank, disinfect, pay attention to not replace all the water, the water can only be changed a quarter to a third at a time. Pour out the fish and water together and put it in a clean basin and then clean the fish tank, and you don't just take the fish directly, the fish is easy to be injured, it is easy to die, you have to buy a net pocket to get the fish, what are you feeding the fish? Can't feed fish feed, feed has no nutrition, and most of them are starch, not easy to digest, it's best if you find a time to dig some earthworms, raise them in a pot, two or three days out to feed a little, look at the size of the earthworm to feed the fish, small fish are like children, they will not control the amount of food themselves, sometimes feed too many fish will die, these are my years of experience in raising fish, I hope to help you, as long as you love the fish with your heart will get better, hehe.

Don't let him eat it, it's best to eat the food in a few minutes each time, and if you eat too much, it will be bad.

It is good to feed the fish once every 3 days, and change the water once every 7 days.

Feed less. If you feed too much and squeeze the swim bladder, you will lose your swim bladder.

The body is unable to balance.

Fish are inactive.

First, you haven't fed in a long time.

Second, if you feed, consider whether there is a lack of oxygen, it is recommended to increase oxygen, pearls are most afraid of hypoxia, and third, the problem of changing the water Even if there is filtration, it is still necessary to change the water once every half a month, and it is not necessary to change it all without filtration, and the water should be changed frequently.

Fourth, keep the water fresh If the above problems do not exist, consider whether the goldfish is sick Observe whether the goldfish has abnormal lesions in the body and prescribe the right medicine Lanshou Net.

I haven't changed the water for a long time. Change the water as soon as possible!

Blackening of the head of a goldfish can be both diseases:

1. Black spot disease.

Diseased fish can see long light yellow sporangia on the head, and when the cysts are mature, they are black, i.e., waging tail larvae and posterior cyst larvae, which also invade the eyes, muscles, blood vessels, gills and internal organs of the fish, and if opaque plaques are found in the lens of the eye, they may be infected.

2. Black spot disease.

Small black or brown spots, up to 2 mm wide, appear on the body and fins, and sometimes on the eyes and mouth.
