Fish farmers are invited in, how to raise fish? The master is looking for a detailed explanation!

First of all, the first point should be that the density of fish in your tank is too large, and there are many fish that can be eaten and pulled, resulting in excessive bowel movements, and the water quality deteriorates. The second point is that you are lazy at the beginning, you should change the water early when the water is not kept up, resulting in the water can not be replaced in time with more impurities, coupled with the high temperature of hot water in the weather, the water body deteriorates rapidly, and the later period can not be seen immediately through frequent water changes. The third point is that the flow rate and suction of your filtration system are too small, and the whole filtration system is too low, resulting in nitrifying bacteria and impurities in the water body that are not proportional to the consumption of pollutants.

Prescription: Add another set of filtration system, don't be afraid of more fish if you want to have more fish, don't be afraid of more equipment. The larger the water body, the larger the filtration, the less likely it is to have problems, and then the next step is to continue to keep two days for one-fifth of the trapped water, pump more impurities under the bottom of the fish tank, filter 24 disappear uninterruptedly, clean the top layer of the old filtration system, and the rest is to wait.

Don't use any water purification drugs or the like, unless you don't want your fish anymore) Note: "Nitrifying bacteria are highly aerobic bacteria, there is no special restriction on temperature, no matter how hot the weather is, it will not die in large numbers, and people in the aquarium may not all understand the characteristics of nitrifying bacteria, if you want nitrifying bacteria to survive well, the least is that the water flow cannot be broken, and it is driven by the water flow to survive!" ”

Recruit me to do it.

Prepare a large basin, fill it with fresh water, put in 2 bags of coarse salt, put some erythromycin, and put the heating rod until the water temperature is 28 degrees. Prepare another basin of water and heat it to 28 degrees.

Fish out your fish and throw it in for 3-5 minutes, during which time pour a little potassium permanganate into the original fish tank, brush the tank, change the water and heat it. There should be a person here to observe the condition of the fish soaked in the potion, and if there is no ability to swim, the reverse swim or reverse swim should be quickly fished out into the basin of clear water.

As soon as the time comes, just put the fish in the original tank, and put some oxygenation on the first day. so as not to lack oxygen.

We have this kind of problem in the workshop, and it's basically not a dead fish, you can try it.

Do a good job of filtration, open all day, the water department can be greatly changed, and a third of it can be changed every day.

Is it a lack of oxygen Do you take oxygen The water can't always be changed And the water has to be controlled for a few days before it can be used You press a filter and then add oxygen Basically don't need to change the water If the water is less, add water to it and add less at a time.

First of all, see how the water quality of your fish is doing! Haven't you been sleepy for more than 3 days? Then see if the jar is too small! When the fish comes to the surface, it indicates a lack of oxygen!

Based on my wife's experience in fish farming, I will answer here:

1。Of course, it is necessary to raise fish that are easy to raise, preferably with strong vitality. Guppies are beautiful, they can adapt to very harsh environments.

You can raise feng shui fish at the door, like silver Arowana, with feng shui attributes, and the price is not expensive. In addition, you can raise peony fish, moonshine fish, glass cats, panda rats, kissing fish, etc., these are all good choices.

2。Equipment in the fish tank: a bottle of potassium permanganate (for disinfection of the tank and equipment), a siphon (for water change), spare various medicines, and it is best to prepare an extra pump or an air pump with a battery.

3。Fish tank decoration: get some small stones, plant two or three aquatic plants, and put some shells and other decorations.

4。Water for fish farming: After a certain amount of technical treatment, tap water is the best breeding water for freshwater ornamental fish.

It cannot be used directly to raise fish. Generally, the cooling method is adopted, and the tap water is placed in an open-air ventilated place, with the help of air circulation and sunlight, the residual chlorine in the water is volatilized, and the amount of dissolved oxygen in the water is increased at the same time. The cooling time is more than 24 hours in summer, more than 48 hours in spring and autumn, and longer in winter.

Then it depends on what kind of fish you raise I raise large carnivorous tropical fish like Luohan Seven Star Knife Crown Blue Shark and so on If you raise this kind of fish, you need an oxygen pump, a heating rod, a lamp, a filter, if you have a filter, you can do without an oxygen pump The fish you raise will die quickly There are several possibilities The fish is not healthy, the water is not clean, the sun is not seen, the space is not circulating, etc.
