Goldfish (definite introduction)
Goldfish is our most common tourist fish, and many families will breed goldfish for observation purposes. , besides visiting, it will also add some fun to the home. If we want to breed goldfish well, we need to use correct methods, and daily maintenance is also indispensable. So, what should we pay attention to when breeding goldfish? ?
1. Raise goldfish first with water
For fish farmers, there are four types of water: one is new water, that is, The tap water that has just been dried out or the well water that has been newly installed. Although this kind of water is very clean, it is very different from the living environment of fish in nature. Since there are no nitrifying bacteria in the water, fish permeates and scattered food residues become rancid and metamorphose into ammonia, making fish easily poisoned. The second is old water, which is light green or light amber in color. It is rich in humus and beneficial microorganisms and algae. It has established a good ecological cycle system. Through the nitrogen cycle, it is converted into nitrates that are harmful to fish. This kind of water is extremely beneficial to the growth of fish. The third is green water. The organic matter content in the water is too much, so cyanobacteria, green algae and brown algae grow in large numbers, and the content of bacterial microorganisms increases sharply. The water is thick green and occasionally smells bad, which can easily cause fish in the entire tank. Die. The fourth is to return to purified water, also called purified water, because there are too many algae and microorganisms in the green water, which consumes all the oxygen in the aquarium, resulting in the sacrifice of algae and aerophilic bacteria, making the water clear, endless, and indistinct. Stagnant water that is oxygenated and has a large amount of anaerobic harmful bacteria.
From this we know that not all water is suitable for the survival of goldfish. The most suitable water for the growth of goldfish is old water. The so-called water maintenance is the process of transforming new water into old water. At present, most of the water we use to raise fish is tap water, so the first step in raising water is to remove the toxic substance-chlorine in the tap water. The method of removing chlorine is relatively simple. Fill the water and let it sit for 2-3 days, or dry it in the sun for 1 day (if it is needed urgently, add 0.63 grams of sodium thiosulfate per 100 kilograms of water and it can be used immediately. use).
After the new water is well-done, it should be put into the tank and the filter should be turned on. Let the pump turn the still water into oscillating water, and then put in the fish that invade the tank. "Into the tank" is to put a few cheap, healthy and easy-to-raise fish into a new tank. After a few days of raising the fish, the fish's feces will produce ammonia in the water. This is similar to the ammonia contained in tap water. , too much ammonia will cause fish death, so the most important thing in raising water is to remove ammonia from the water. Often we use nitrifying bacteria to remove ammonia from water. Nitrifying bacteria can be introduced into the water, but theyThey need attachments to survive in the water. If there are unsuitable attachments, no matter how much nitrifying bacteria are added, they will not be effective. They will die in the water. Nitrifying bacteria often attach to the filter cotton or bottom sand. It turns out that nitrifying bacteria will naturally produce nitrifying bacteria after a certain amount of time in water that has been exposed to water. This is also the most commonly used method for cultivating nitrifying bacteria. < p > , often swim slowly on the surface of the water, not in groups. If there is vibration, they will sink slightly and then surface. There are also some fish that swim wildly and scurry around when they first become ill, or their body color is dull and their scales fall off, etc. Another example is that after the white crucian carp hemorrhagic disease broke out, wild small fish in the early fish ponds were sacrificed. When signs of fish disease are found in a fish pond, immediate measures should be taken to prevent the disease from spreading.

3. Reasonable and Scientific Use of Medication< /p>
Commonly used drugs for fish diseases each have their own physical and chemical properties, so attention should be paid to rationalization during storage and use to avoid drug waste due to improper storage and use. For example, which drugs can only be taken suddenly, which drugs are effective when taken internally, and which drugs are not suitable for use. Which drugs will be more effective, which drugs will be affected by environmental factors, etc. The bait should take into account the living habits of the fish and create different baits such as floating, sinking, and particulate. Generally, when green carp, carp, and crucian carp are sick, they should be fed with heavy-duty chemical bait; when grass carp is sick, it is better to feed floating bait or mixed with medicine on aquatic plants; when silver carp is sick, it is better to feed particulate bait, which should be mixed in when found. A certain amount of adhesive to prevent the drug from being lost in water. When pouring medicine, the medicine should be fully melted and then poured evenly into the whole pool. The best time to pour is in the afternoon, because the water temperature is high in the afternoon and the medicine is highly effective. When pouring medicine, pour it gradually from the advantageous position to the downwind position. The remaining unmelted medicine after pouring cannot be poured into the pool. Otherwise, the fish will be poisoned and sacrificed if swallowed.
Four. Important matters for goldfish farming
1. Food should be stopped for 1 day before feeding with chemical bait, so that the fish are in a hungry state, and the fish should be fed with chemical bait. After feeding, you can eat quickly.
2. During the treatment period and just after the fish is cured, it is not advisable to change a large amount of water and fish, so as not to cause irritation to the fish, cause stress reactions, aggravate the condition or cause recurrence.
3. To control fish diseases, measures should be taken to combine internal and external administration. Simply relying on oral medication will not work.The efficiency of attacking from both inside and outside.
4. When treating fish diseases, the same drug cannot be used repeatedly to avoid causing the disease body to become resistant to the drug, and the drugs should be used alternately.
5. Once the disease occurs, no matter how effective the treatment is, damage cannot be avoided. Therefore, it is often necessary to maintain a prevention and control plan of "prevention first, regulation as a supplement".
Place the glass jar near a window where it is ventilated and sunny. It is necessary to pay attention to the stocking density and arrange it reasonably according to the size of the container. Rather than raising too little, it is better not to raise too much. Because the indoor air is not very fluid, the water will become dirty if raised too much, which can easily lead to the death of goldfish due to lack of oxygen. If there is an air pump, you can raise more goldfish. If you find that the goldfish has a floating head, you need to turn on the air pump for oxygenation, especially at night.
The most ideal bait for fish farming is live fish and worms. The water quality is not easy to deteriorate. You can also feed fish and worms or synthetic pellet feed. Currently, live fish and insects are sold in the market, but it is troublesome to buy them every day. Regarding the fish and insects sold in the market, you should choose relatively fresh ones with loose particles to feed fish, and do not buy stale and moldy fish and insects for feeding. For artificial pellet feed, it is better to use full-price feed with complete nutritional content, which is available in the market.
In order to maintain the purity of the water, the amount of feed should be quantified strictly and on time. It is usually appropriate to feed once or twice a day. The amount of feed should be eaten within half an hour. Do not overfeed. too much. There are two disadvantages of feeding too much: first, if the fish eats too much, their metabolism will increase, and their oxygen consumption will decrease, which can easily cause the goldfish to suffer from hypoxia and die; second, if the bait is left, it will easily go rancid and ferment, causing the water quality to deteriorate, and the fish will also die. Create hypoxia. It turns out that goldfish are relatively resistant to hunger, and no problems will occur if they are not fed for a week or two.
It is crucial to keep the water pure when raising goldfish. You should often use a latex tube to suck out the accumulated residue, suck up the feces and residual bait at the bottom of the glass tank and clean the polluted water, and then slowly replenish the accumulated water. Fresh water all day long. If water plants float or the rockery is knocked down during operation, restore it to its original state immediately.
The longer you keep fish, the more sediment will accumulate. Although it is cleaned every day, it cannot be completely cleaned. If the sediment increases and affects the clarity of the glass tank, it is necessary to completely change the water and clean the glass tank to keep the water pure, convenient for observation, and to maintain a good living environment for the goldfish.
Due to their small size, the commonly used rectangular glass jars cannot be kept in large quantities, so it is better to have less and not more. For example, in a container with a length of 40 cm, a width of 25 cm, and a height of 30 cm, 6 to 8 goldfish with a length of 5 cm to 7 cm can be raised. Adult fish with a body length of more than 8 cm should not be kept in small glass tanks, but should be kept in luxurious large glass tanks or ceramic tanks with a small oxygenator as standby to prevent hypoxia. The above stocking density is only a reference. It depends on the water temperature, the size of the fish and the quality of the water to make a decision. It cannot be done in a rigid manner. Generally speaking, fish are large and should be raised sparingly; they can be raised more in winter and less in summer; they can be raised more when the water temperature is low and less when the water temperature is high..
The breeding of goldfish is relatively simple compared with other guinea pigs, but it is easy for us to raise goldfish regularly. If we want to raise goldfish well at home, in addition to paying attention to the above four things On the other hand, details such as feeding, changing water, cleaning, etc. of the fish cannot be underestimated.
