Seek help from a professional tropical fish expert urgent, urgent, help, preferably in Southeast As

Adjust the density of the fish, some fish will attack each other when the density is too high, it is normal for small fish to die, medium and large fish die every day, it means that there is a problem with the master's technique.

The fish you raise has a high temperature regulation, the water temperature is high or low or low will lead to death, it is best to control the water temperature with a heating rod, and then store the water for a day and then give the fish, add a little salt, just play a role in disinfection, 20 hours a day are oxygenated, the saury is a fish that feeds at night, put a little small live fish or shrimp, add some fish food, and you will eat it after a while, if you don't eat, you are not familiar with the environment or the density of fish is too much, you have to separate, don't be anxious, take your time, Learn more about tropical fish farming. The water temperature is controlled at 22-28, and the body surface can be seen if you are sick, such as the gills of the fish are ulcerated, and the fish body is injured, so it is necessary to prescribe the right medicine, and it is recommended to ask a breeding expert. Oriental knives should be kept separately from other carnivorous or small fish, otherwise they will kill each other and lead to death, so it is recommended to keep one species of fish in each tank.

The temperature of the hot rod is 29 degrees, and the thermometer shows the temperature of 32 degrees, which is normal, and the temperature set by the heating rod is generally two degrees higher than the temperature of the thermometer. Another reason is that the cylinder has no lid, and the temperature of the lid will be higher, with a difference of three degrees.

The yellow color on the filter cotton may be the residue of potassium permanganate, you can try to add vitamin C first, usage, just take a piece and put it in the yellow place on the filter cotton you said, and see if the yellow will disappear the next day, if it disappears, add a few more pieces to the tank to neutralize potassium permanganate.

Generally speaking, it is said that after seven days, the fish will be reopened, in fact, the third to four days may be released, but do not put the fish, now the nitrification system is impossible to establish, put a fish into the tank, raise three to four days, nothing to do, just put other fish.

New water plus nitrifying bacteria will definitely muddy water, and it is new water and nitrifying bacteria, and it will gradually clear up after about three days, and it will still be the same muddy after three days, but the clarity is much better, observe more.

It's not that the bacteria are not put away, it is how your filtration system is, whether the bacteria house is enough, you can put more digestive bacteria, and there is no suitable environment for nothing.

There are so many questions.,I'm tired of typing.,Hehe.。。。

Don't put nitrification anymore, you filter and turn on the oxygen, and after 2 days the water is clear and you can release the fish.

What kind of filtration are you, the water mixture does not cultivate nitrifying bacteria well, it takes 20 days to cultivate nitrifying bacteria well, that is, the water will be clear, and your case nitrifying bacteria must be put.

If the water temperature is not enough, the resistance will drop! Most tropical fish are around 32°-36°... Do you raise fish? The thermometer is just relative! It doesn't mean it's really that temperature.

1.Acidity, alkalinity and hardness If you have money, you can buy bottom mud ADA, grass mud pills, etc. or sunken wood (the above is expensive but can be reduced to acidic water for a long time), black water can be quickly adjusted If you use mineral water, please dry it first, in order to prevent the lack of dissolved oxygen in the water.

2.Not enough, aquatic weeds should occupy more than one-third of the water body.

3.The temperature of the fish tank should not exceed 31 and be lower than 21 degrees, if you have an air conditioner indoors to ensure the temperature, you can do not add or cool down the equipment.

4.The water change depends on the water quality, some tanks are well balanced, and the water quality can be maintained at a long interval, on the contrary, it is short Generally, 3 to 7 days in summer to change one-sixth of the water, of course, if the water quality of your tank is maintained very well, you can change the water for a longer time.

5.If there is filtering, no problem. If not, it's half less.

Other basic things that should be noted:

1.Don't fish more tanks small 1 liter of water (length, width and height 10 10 10 cm) raise 1 cm fish, goldfish centimeters, more will be very easy to get sick and die. The tank should be at least 30 cm or more to maintain the water quality, or the method of calculating the fish according to the water surface area, tropical fish need 30 square centimeters per centimeter of body length (excluding tail fin) and goldfish need 60 square centimeters.

2.Open the tank to raise water should be disinfected with salt and then washed, the water in the tank should be raised for 7 days, put into the strong vitality of the tank fish for 30 days, the temperature should be between 28-30 (or after entering the tank fish 3 days plus daily nitrifying bacteria for a total of 7 days, pay attention to avoid light) (or to "three bacteria open the tank", but pay attention to the appropriate amount, rather less, pay attention to avoid light and gas) (or during the water retention period in the filter tank immersed in the water a peeled raw shrimp until the shrimp completely melted off), there is filtration during the opening of the tank can not be stopped, 20th, It is best to release the fish after more than 30 days. Also, don't let direct sunlight shine on the fish tank!

A in this article () is to say that there are conditions to need to use nitrifying bacteria for fish or people b In addition, after opening the tank, the usual temperature of the fish should depend on the species, survival, and other needs of the fish and aquatic plants to be determined c After the water is clear, the fish tank should have light but not direct sunlight, and the survival place of nitrifying bacteria such as the filter tank must be protected from light and breathable (if it is an internal filter or an external filter barrel, it can not be stopped, if the power is cut off for 2-3 hours, there is information that nitrifying bacteria will begin to die, and if the water is not soaked, the upper filter is 8 hours, and the drip is 12 hours)

3.When releasing the fish, pay attention to the fish and the bag should be put into the tank together, after 15 to 30 minutes, go to the water and the bag, the naked fish into the tank, during which the water in the tank is added to the bag several times to make the fish adapt to the first day not to feed.

4.Water Change The water change should be based on the quality of your water. If there is filtration, it can be less, no filtration can be more, and the water should be dried, and one sixth of it should be changed each time.

It takes about 10 to 20 days in winter and 5 to 7 days in summer. Therefore, the advantage of having fewer fish in the tank is that there is less water change and the water quality balance in the tank is well grasped.

5 food within 15 minutes to eat one to two times a day can not have oil do not fish shop the cheapest red and green grains,

You first plant aquatic plants to plant aquatic plants before you start raising fish, only water banyan is not enough, it is best to plant some wood silk and the like, in addition I don't know what kind of base you use, you can use PH paper to test the water, if the hardness is too high or not enough, you can use different brands of mineral water (there are five liters of a barrel is only a few yuan a barrel) to add to adjust the pH value, but not too deliberately pay attention to the hardness of the water. The most important thing is that the water filtration work must be done well, and the filter cloth must be washed regularly. There are also unwanted fish can be given away, if it really doesn't work, it will be sent off, do not release it at will to avoid affecting the normal ecological balance, (such as Fushou snail) you will not want the fish store at a low price, because different batches of fish will have different bacteria, and it is easy to cause extinction if you accept new fish.

As for winter, it is not lower than 18 degrees, and generally there is no need to use a heating rod. Changing the water once every two weeks is sufficient, up to a third of each time. Many fish are changed to death.

Disinfection of the cylinder is a must, but it is not too troublesome. Fill it with potassium permanganate and soak it for 30 minutes to 1 hour, drain the water and then wipe the tank, it's very simple.

Water farming is also necessary, fish farming first water farming, the main purpose of water farming is to remove chlorine and heavy metals from tap water. In this way, the fish can live comfortably. Generally, if the tap water is out for more than 3 days, it is actually no problem.

If you raise fish, the most important thing is the daily maintenance work, and it is best to change the water that has been raised, and the temperature difference is not too large. Some nitrifying bacteria can be added appropriately every time you change the water, but the large tank is generally filtered at the bottom, and the effect of cultivating nitrifying bacteria is very dry. Then there is the density of fish farming, if your tank is more than 2 meters, then it should be no problem to raise 4 or 5 Arowana, if it is the best rice, don't raise more, one can be.

Mix some other fish. If there are too many large fish, the water quality can easily deteriorate, and if the water is not changed frequently, the fish will die frequently.

Don't pour a lot of coarse salt into the jar when it's not necessary, it's no good. Changing the water once every 3 days is fine.

The new tank must be sterilized, my 1 meter 1 bullet, when I filled with water and potassium permanganate soaked for several days, and then washed, opened the lid and cooled for a few days, the new tank is mainly gum smell, if the conditions permit, go to the balcony to bask in the sun, add water after the end, do not add boiling water all tap water, open the cover, circulation, 3 days after the salt fish, it is best to raise less, can not add fish every three or five differences, it is best to be the same store in the same batch. When changing the water, look at the turbidity of the water, pump two-fifths, don't change it all at once, I took the tap water on the balcony for backup, and when I changed it, I pumped it out first, and the water that was prepared was good. If the drainage is too tired, you can find a long pipe to connect Huisen directly to the bathroom.

Precautions. 1. The water must be dried for at least 2 days, because there is chlorine that needs to be volatilized.

2. Salt to the aquarium store to buy, it does not contain iodine.

3. Put cotton on the magnetic ring in the filter tank. Activated carbon is mainly deodorized, and the new tank should be placed. These should be cleaned regularly.

4. Salt is sterilized, and digestive bacteria are eaten with fish feces, which can be added together. 360 words add semi-tremor Biyun package salt eggplant beam can be, digestive bacteria have instructions.

5. Arowana will bite, it is recommended not to raise too much, just start raising general, such as maps, parrots, etc. Cheaper, less loss. It is recommended to prepare yellow powder and white spot net (all powdered sachets). Apply as directed.

Hello, it's not interesting to copy to you, I've been raising fish for 3 months, and my current tank is also 1200x500x700

Let me tell me the order of my fish raising, you already have fish in the tank now, I generally open the tank very quickly, first the tank is drained, add potassium permanganate disinfection, and the second Gao Lutian will pump away the water with potassium permanganate, in the release of water, it is all tap water, put some to pump some, desalinate the potassium permanganate in the tank, and then look at the almost, directly put the water in the tank. Now let the water stand for two days, volatilize the chlorine in it, (note, if you want to put the aquatic plants before the water, you have to put it before the water,) I don't know what method you use to filter it, at this time the water swimmer I generally don't have a lot of fish into it, I will put two scavengers This kind of fish, or the market sells the kind of small fish that feeds the cat, live, this is called breaking into the tank, put it in to observe for a few days to see if there is a problem with the water quality, pay attention to the filtration has been on, generally after a few days there is no problem, you can buy fish and put it inWhen you put the fish, put it in the water together with the bag, so that the water Qi Mo is the same temperature, and then it is over the water, which means don't put the fish in the tank at once, and the water is that you put a little water in the tank into the bag, and put some of the water in the bag into the tank, little by little, and so on. It feels almost, let the bag sink to the bottom with the fish, let the fish swim out on its own, I don't understand to ask me, I'm just a novice, but I didn't have any major problems in the process of raising fish, hehe.

The most important thing is that the temperature must be kept good and the water should be clean.

Breeding method of tropical fish: tropical fish need to be provided with suitable feeding space when breeding, and need to be fed regularly; Precautions: Tropical fish have strict requirements for water quality and are particularly sensitive to temperature changes, most of them can adapt to the water temperature of 20-30 degrees, and it is not easy for most tropical fish to survive outside this range.

Tropical fish are born in the tropical waters of Binzheng, and tropical fish are divided into freshwater tropical fish and saltwater tropical fish.

The hometown of tropical fish is mainly in Southeast Asia, Central America, South America and Africa, among them, the Amazon River system in South America produces the most species, the most beautiful form, such as the queen jujube angelfish known as the tropical fish, Malaysia, Indonesia, Sri Lanka, Thailand, Myanmar and other countries, there are many types of tropical fish.

1: There are pros and cons to using those two kinds of water, the advantage is that you don't need to raise water, you can use it directly. The disadvantage is that there is nothing in this water, no oxygen, no microorganisms.

There is a saying: When the water is clear, there are no fish. If a person has been living in pure oxygen, then this person will not live long. The same goes for fish.

2: The thermometer can be yes, but don't you think it looks too cumbersome? And there is a way to fix it in a fish tank. When you go to buy fish, ask the boss to give you one.

3: In winter, it relies on electric heating rods. If your family lives in the Northeast, you can wrap the filtered water pipe around the heating pipe, so that you don't need a heating helper. Another way is to use it in the fish shop, put a briquette stove in the room with a fish tank, which is more expensive.

4: First of all, the fish to be produced should be isolated from other fish, and it is best to keep them in a small tank alone. Nothing else is special, you can feed a little better.

For example, give the mother fish something red blood worms to eat to increase its nutrients. In addition, after putting the fish into the small tank, the small tank should be changed as little as possible to avoid discomfort caused by water quality changes.

Then you have to put obstacles in the tank, which is where the little fish can hide.

It's best to put more aquatic plants. If you don't have one, put some decorations in the water, like those little houses that decorate fish tanks, shells, etc. Not really.

Just put more stones in the water, rain flowers and stones, and spread them all underneath. This way, even if the mother gives birth late at night, you don't have to worry about the baby fish being eaten. Then get up the next day and put the mother fish back in the big tank. The small fish are raised in this tank.
