Tropical fish problems, water quality problems for raising tropical fish

Fish float on the surface of the water because of the lack of oxygen in the fish tank, maybe your bathtub area is too small, there are too many fish in it, it is recommended to change to a larger fish tank or separate a part of the fish to other fish tanks, it is best to add a filter in the bathtub that can filter sewage and effectively increase the oxygen content of the water. White spots or white hairs on the fish are a problem with water quality, and bacteria or parasites in the water cause ulcers on the fish's body, as follows:

1 The bait must be clean. Feeding unclean bait can easily lead to fish diseases. It is recommended to buy branded frozen fresh food produced by professional companies, such as blood bloodworm and prawns, supplemented with beans and vegetables to maintain comprehensive nutrition.

Although live food is the favorite of tropical fish, live food is grown in a polluted water environment, and there are a large number of pathogenic bacteria on the body, and live food is also very easy to die, and it will also pollute water quality, so it is necessary to be cautious when putting live food.

2 Keep the water clean. Fish eat a lot of food, consume a lot of oxygen and excrete a lot of waste, which pollutes the water, breeds pathogens, and causes tropical fish to die of diseases. In order to keep the water clean, a filter should be installed, and a tenth or a little more of the old water should be removed every day while the effluent is removed from the bottom of the tank.

Filtration with aeration can be used, which is carried out at the same time as filtration and aeration, so that the water can be purified and oxygen supplemented.

3 Do not bring grease into the water. The oil will float on the surface of the water to isolate the air, so that the oxygen in the water cannot be replenished, which will cause the goldfish to die of lack of oxygen. Eating meat or applying hand cream to your hands can bring grease into the water and should be carefully avoided.

4. The establishment of Shengda type filtration system can effectively improve the water quality, and the harmful substances in the water can be decomposed into harmless substances by microorganisms, and even become nutrients for aquatic plants.

5. If conditions permit, it is recommended to plant aquatic plants densely in the tank, and a large number of aquatic plants can be combined with a good filtration system to keep the water quality stable.

6 Finally, it should be mentioned that it is essential to replace the old water with 1 3 1 4 old water once a week to replenish the new water, and the water quality can be activated by changing the water, which can reduce harmful substances and stabilize the water quality.

**] of the white dots on the body of the fish: 1. It can also be soaked in 5 salt water for several days; 2。

or 2 parts per million (2ppm) of methyl blue solution, soaked for 6 hours a day; 3。Mixed with 0.05 parts per million (malachite green and 25 parts per million (25ppm) formaldehyde solution, the efficacy is better; 4。or soak in 28 30 parts per million (2ppm) of quinine hydrochloride solution for 3 5 days; 5。

or soak in two parts per million (2ppm) of mercurous nitrate for 30 minutes; 6。or soak in a red mercury solution of fifty to seventy parts per million (50 70 ppm) for 5 15 minutes, 2 times a day.

Fish don't sleep. Tropical fish are more troublesome to raise. My family used to raise a lot of Arowana and silver Arowana.

In a long blackout, it all died. I almost fainted. And finally I looked at the books and found that tropical fish are not only afraid of the cold, but they are also very picky about the quality of the water.

So I think your symptoms have something to do with water quality. It is recommended to buy some special drugs for tropical fish to prevent infectious diseases, and pay attention to the cleanliness of the fish tank. This is the most critical.

White spot disease And to correct it, the fish are sleeping, you can first adjust the temperature up about 31,2 degrees, not too high, go to the fish market to buy some **white spot disease medicine, or add table salt to the water, it is better not to feed.

It doesn't have to be complicated, and the water temperature is adjusted to 25° above 30°.

24-hour feeding filtration (maybe your tank is short of oxygen, change to a larger oxygen) go to the place where the fish is sold to buy a bottle of white spot net.

10 yuan, a better 15

It got better in 2 days.

Turn the heater up 2 degrees and bubble each fish in the brine in hopes of eliminating the white spots.

Add a pinch of salt! The temperature is set to 30!!

Hehe, hello, don't pay too much attention to the popular saying now, for example, the "three-bacteria opening the cylinder method", which has been very popular in recent years, is the representative, and it is necessary to pour yogurt when opening a fish tank! It's called cultivating probiotics! Aren't you too talented!

Small fish like peacocks, Mary, Lili, etc., have much stronger vitality than many ** big fish, and they are just as interesting to raise!

Don't mind the pH too much, these small fish are absolutely fine with sleepy tap water, and as for nitrifying bacteria, how many fish shops will use them themselves? It's all sold to consumers, isn't it......

Not much advice can be given to you, but it should be useful :

1. Try to keep your tank away from the sun, too much light is not good, algae is a trivial matter, raise a few scavengers.

2. If there is no filter, it is also recommended to change the water twice a week for raising small fish, and remember to be sleepy for a few days and release chlorine gas for fish farming in tap water.

Have fun!
