Why do raised fish die within a few days? Is it because I don’t know how to raise fish? Or is there something wrong with the fish species? Comprehensive analysis of the causes of “dead fish”, let’s see how many have you won?
Why do you always raise fish to death? If you don’t learn the basic knowledge of fish farming before raising fish, you will think that raising fish is too simple! Ornamental fish are the most difficult pets to keep on the planet. If you mistakenly think that “fish only need water to survive,” then you still think of water too simply.
How to raise fish? If you want to solve the problem of “how to raise”, you must first solve the problem of “why you don’t know how to raise”. The first step in raising fish is to learn, the second step is to raise water, and the third step is to buy fish.
Raise fish first and raise water
First, you should focus on the water, not the fish. Fish cannot leave the water, but fish cannot be raised in any water. Nitrifying bacteria must be cultivated in the fish tank water before fish can be released. The growth of nitrifying bacteria cannot be separated from the help of filter materials. If your fish tank doesn’t even have filter material, let alone water maintenance. Without filter material, you don’t know how to maintain water, so the fish will die!
Suggestion:
1. Before changing the water for fish farming, collect the water to be changed the day before, leave it for one day, and then change it the next day.
2. Buy a filtered oxygenator and leave it on 24 hours a day to increase the vitality of oxygen and water.
3. Feed less fish food. Change the water frequently and don’t change too much at a time.
4. If possible, plant a hydroponic plant on top of the fish tank.
5. Raise small fish, not too many, three or five are enough.
The reason why all the fish died, how many fish did you win?
Category 1: Equipment issues
- The heating rod fails and the fish is boiled
Water temperature and water quality are the most important things for ornamental fish to pay attention to. If you rely on a heating rod to maintain the water temperature, once there is a problem with the heating rod, your favorite fish will become a delicious “boiled fish” by accident, so be sure to choose A highly reliable heating rod! Don’t let the facilities lead to fish tragedy!
- Plastic is toxic
Do not use plastic products casually in the fish tank. You may have bought a plastic that is not food grade to save trouble. Not only is it ugly, it may also be harmful. Such harmful substances may not have any impact at first, but they are a chronic killer. Don’t talk about how well fish can be raised due to water pollution. You must be careful and don’t lose the big for the small.
- Meat grinder filter
The water inlet and oil removal film port of the filter are places where fish often die. The upper small fish are often sucked into the oil film port and minced into meat paste. Some small fish with weak constitution are also easily sucked to death by the powerful filter, especially if it is a newly hatched fry. Friends who use waterfall filters to raise guppies generally encounter similar problems.
- Partition
It is still impossible to isolate fish that are very specific to the area, and fighting in mixed cultures is still a big problem. The most common way is to separate them with partitions, but if you are not careful and the partitions are not properly separated, it is very possible to have a big fight later.
- Inadequate filtration
Don’t take chances when it comes to the filtration used in fish tanks. Many old people think that the filtration is weak and they just need to change the water frequently. Many newcomers have no idea about filtration and think that as long as there is a piece of cotton and water flows, it will be enough. How many fish you can keep in a tank depends on the performance of your filter. There are too many explanations about filtering power and flow rate on the Internet, and so many documents prove how necessary it is to choose a reliable filter.
- Attention should be paid to the cylinder head
There are no more than three reasons why fish jump out of the tank: 1. Severe lack of oxygen. 2. To be frightened. 3. The water quality is extremely unsuitable, or the temperature difference during water change is irritating. Of course, some fish are born to love to jump, the common ones are koi, grass goldfish, arowana, etc., so if you raise a fish that loves to jump, you must cover it. If possible, you can also add a network.
- The thermometer is broken
The liquid in fish tank thermometers is usually alcohol or kerosene. When the thermometer breaks in the water, the broken glass is difficult to clean in the water. The liquid in the thermometer will pollute the water quality. Whether it is kerosene or alcohol, it is very harmful to fish. If the thermometer is broken, a tank of water is basically useless.
Category 2: Fish habits
- Cannibalism
When animals are placed in the same small environment to survive, especially when they are hungry, they may behave abnormally. Some fish are territorial and will be beaten to death if kept together.
- Fish hits the tank
There are probably several reasons for the fish hitting the tank: there are dark forces! There is a certain fish that is the dominant fish in the tank and seriously threatens the living space of other fish. I was frightened by people, rude people patted the fish tank randomly, naughty children fished for fish, etc.
- Large mixed culture
If there are turtles and lucky fish in the fish tank, you must be careful when adding new fish. There have been many failed examples of turtles biting fish, so I won’t list them all. Lucky fish is easy to raise, not picky about food, has a good metabolism, and is known as the God of War. Even turtles can swallow it, making it the top of the food chain in the fish tank.
Category 3: Human issues
- Replace the filter material in one go
Change or wash the filter media at once on a whim. The water quality is violently oscillating, the digestive system is collapsing, and some filter materials are acidic and alkaline. It’s no wonder the fish are not in trouble!
- There is washing powder in the water change bucket
Don’t ignore this issue! Very few people use a bucket alone to change water. Many people use whatever they find. Maybe the bucket has been used to soak clothes before, and there is washing powder left in the bucket. Check your container every time you change or refill the water.
- Water change contains chlorine
Tap water needs to be periodically cleaned and disinfected every year in the pressurized water storage tank and pipes. After cleaning, the concentration of chemicals in the water supply is very high. If the water smells too strong and turns white or the water has poor transparency when placed in the fish tank, do not change the water first. Yes, for the same reason, don’t change the water on rainy days. For the sake of your beloved fish, be more careful!
- The new fish is too full after arriving home
New fish are sent home for quarantine, and the fish are allowed to adapt to the environment as much as possible after crossing the water. During this period, they are generally not fed for fear of acclimatization and diarrhea. During the isolation period, observe that the fish’s body surface is normal and that there are no parasites or intestinal diseases. When the fish shows strong food-seeking behavior, start feeding a small amount and gradually increase the feeding, because you do not know how much the fish eats. Feeding too much can cause enteritis. Feeding slowly, knowing how much the fish eats, and feeding according to the food amount is the correct way.
- Feed live food
Live food is a kind of food with high nutritional value, and it is also a kind of bait that fish like. However, many live foods themselves have parasites, so they should be fed in small amounts. It is okay to eat insects as snacks, but when the staple food is not very good, it is recommended to mainly eat completely processed meat or feed.
- Indiscriminate drug use
When the fish is sick, it understands that the owner will be anxious. Asking people everywhere, it makes me confused. In the end, I took some medicine. A few days later, the fish passed away, and I regretted it. When a fish gets sick, calm down as soon as possible and think about the reason. Most fish use the “old three” to hold it up first. If it doesn’t work, ask a reliable person. The fish medicines on the market are also mixed. You must buy them through regular channels. Don’t believe in any “universal medicine”. If there is such a thing, do manufacturers need to produce other medicines?
- Wire strip
No matter how busy or tired you are, please take 10 minutes to check the wiring of the fish tank. We always pay attention to the quality of the fish, the water quality of the fish tank, the flow rate of the water pump, and the perfection of the nitrification system, but how many of us have ever cared about the wiring? If there is no power in the fish tank, everything will be cloudy, so be sure to check whether your power strip is solid, or loose and whether there are any human factors.
Category 4: Natural Questions
- Enteritis caused by overfeeding
Enteritis caused by overfeeding is a relatively helpless problem. Ordinary people will become obese if they eat too much, causing problems such as “three highs”, not to mention fish. Therefore, before raising fish, all aquarists should learn more about the eating habits of fish, and it is necessary to stop eating appropriately. A balanced diet is the long-term solution to fish farming.
- Parasite
One day, the belly of the fish swelled up. I thought it was “ascites” and it might be caused by internal infection. As a result, the fish died due to the indiscriminate use of medicine. Some fish were even less resistant to the drug. There are three poisonous parts of the medicine. Before using the medicine, you must fully understand the tolerance of each fish and the mildness of the medicine.
- New fish may be injured and cross-infected
When buying fish, don’t be greedy for cheap, and don’t buy diseased fish (unless you are sure to cure it). You can’t guarantee that the fish is disease-free. Once it is cross-infected with your fish, you will lose both your wife and your army.
