The goldfish don t eat, and the fish tank has white strips of cotton wool like floats, what should I

Feed less. People who have just started raising goldfish are always afraid that the goldfish will not be full, and they are fed bait several times a day, and the goldfish rarely eat in a state of hypoxia, and the remaining bait is rotten in the water, which aggravates the state of hypoxia. Therefore, to feed goldfish, we must master the principle of small amounts and many times, how much to eat, how much to feed, and not to feed if you don't eat.

Feed once a day, eat within 5 minutes each time, and never feed more.

You can't die if you don't feed it, you just grow it slowly.

You can raise a small amount of aquatic plants in the fish tank, and the green algae in the water is enough for the nutrition of goldfish.

Second, usually pay attention to the water cleanliness, but do not change the water too often, change it once every three days, with the water that has been left for more than three days, each time the original tank water is changed 1 3, the small tank can be changed more.

3. Goldfish belong to the high oxygen fish, easy to tank oxygen, usually observe more, when the fish floats the head, pay attention to oxygen or appropriate water change.

Fourth, personal experience.

After each water change, sprinkle some salt on the goldfish to kill the bacteria.

Now that it's hot, don't put the fish tank on the balcony to expose it to the sun, the water in the tank is easy to rise a lot, and the fish will get sick. Now this season, goldfish are prone to problems. A few days ago, my belly-flapped fish was sunburned and died.

Goldfish are a common disease.

1. Common diseases and diagnosis of goldfish.

Common diseases of goldfish mainly include gill rot, erection scale, water mold, wheel worm disease, melon worm disease, ring worm disease, fish lice disease and non-parasitic fish disease chlorine poisoning. The diagnosis of the disease is based on the symptoms presented, which are done by visual examination.

In patients with gill rot, the gill filaments rot.

In patients with erect squamous disease, the scales are erect like loose balls, and the squamous sac is filled with exudate.

In the case of water mold, "white hairs" (external hyphae) visible to the naked eye grow in the later stage of the body surface injury.

In case of melon worm disease, white dot-like vesicles may appear on the body surface of goldfish. Goldfish suffering from fish lice disease are restless in the water, and their bodies are parasitic with flat fish lice of different sizes in the shape of rice grains, and there are many of them.

The diagnosis of cycloworm disease and ring worm disease must be confirmed by microscopic examination because the worm is small and cannot be seen by the naked eye, and the lesion has no obvious symptoms. The former was sampled with gills and ** mucus, and the latter was sampled from the gills (a little gill filament), placed on a glass slide, water was added, a coverslip was covered, and then a large number of worms were observed under a low magnification scope. Chlorine poisoning, on the other hand, is often caused by the injection of excessive amounts of unchlorinated tap water, which is characterized by a large number of deaths.

Hello!It is enteritis, you may be fed unclean food, or too full of food, in 100 kg of water with dysentery 3-4 tablets, soak for 24 hours, then change to half of the new water, no dysentery Trane can also be used oxytetracycline, the usage is the same as above. Be sure to stop eating while taking a medicated bath.

If it helps you, hope.

The white flocculent presence on the head of the fish is due to water mildew and needs to be used as soon as possible**. You can soak the diseased fish with malachite green or methyl blue solution, or soak it directly in salt water, and the mycelium will fall off after a few days. To prevent water mildew, it is necessary to control the water temperature and water quality, and replace the water one at a time, and the new water can be used only after chlorination.

The white flocculent matter on the head of the goldfish is due to water mold, which is caused by wound infection, and the white flocculent is the hyphae. This indicates that the bacteria have invaded the body and may then ulcerate, and it needs to be done as soon as possible**.

You can soak the sick fish in malachite green or methyl blue solution for 10 to 20 minutes at a time, and after a few days, you can see the mycelium fall off. It can also be soaked directly in salt water, 5 to 10 minutes each time.

Water mildew disease is mainly related to water quality, and the water temperature should be controlled when changing the water, and a part of the old water can be replaced each time, so as not to make the goldfish unadaptable. Tap water cannot be used directly, and needs to be exposed to the sun or left for a few days to remove chlorine.

The details are as follows.

1. A large number of ornamental fish.

The mucus on the surface of the body is shed.

In the process of raising ornamental fish, we will definitely find that these so-called flocculents or biological flocs and the like, before the ornamental fish enter the tank, it can be said that there is almost nothing, the so-called have, but also the water body of the fish tank is placed for too long, the thermometer or heating pipe and the water pipe for oxygen supply will have a little bit of a star, the tank wall should be clean and clean, we only talk about white flocculent here, not to talk about brown algae.

Or green algae. So what about all these things that came out of the **?The first possible reason must be that the mucus on the surface of the ornamental fish has fallen off a lot, that is, either the ornamental fish are not adapted to the water quality at all and are lying in the tank en masse, or the ornamental fish have developed diseases, and symptoms such as water mold and blindfolds have begun to appear.

At this time, the mucus on their body will fall off and float in the water of the fish tank, and then adhere to the tank wall, because the filter cannot be filtered out at all.

2. Water purifier or nitrifying bacteria similar to water purifier.

This can't run, the water quality of the fish tank should be relatively fresh, if it is the state of the ornamental fish is also very good, ** so many flocculents? This is a problem that simply cannot be possibly possible.
