Points to consider when raising fish at home: water temperature and quality issues, environmental factors, biological factors, issues with the fish themselves, and problems with human origin.
1. Temperature and water quality issues. Generally, there is no problem if the water temperature is constant. The fish has a self-cleaning function. As long as it's not particularly mixed, it's not a big problem. Generally, it is enough to change the water every three months. . In the case of light and heat, ordinary fish do not need it.
2. Environmental factors, the most fundamental is water. Sometimes the temperature drops due to sudden changes in the weather, and the water temperature drops suddenly, which can easily lead to fish intolerance. At the same time, there is also water quality, which means that everyone must peBe sure to change the water in time.
3. Biological factors. Generally, fish are attached by various bacteria or algae when purchased. Some biological factors harmful to fish can easily lead to fish death.
4. The problem of the fish itself is like the problem of age. Just like humans, fish's resistance decreases when they reach a certain age, making them more susceptible to disease. This makes the friends take more care of the fish.
5. Human-caused causes, such as a power outage in the aquarium causing the fish to become hypoxia, or accidentally injuring the fish during water changes and causing bacterial invasion.
Prevention and treatment of fish-related diseases:
1. Fin Rot Disease
Fins are damaged, discolored and dull, with foreign bodies in the rot. zone, or fireTransparent fin blades. The white color gradually spreads; in severe cases, the fins are incomplete or unable to stretch. This disease is more prevalent in summer. Tropical fish have thin fins and are easily bruised and broken, leading to this disease. Treatments such as salt and antibiotics may be used.
2. Cottonmouth Disease
Also known as rotten mouth disease. The sick fish has white, cotton-like hyphae growing around its mouth, also known as white mouth disease. Fish that often touch and lick the tank wall with their mouths to eat algae are susceptible to this disease and are easily infected. Sick fish have difficulty eating, swim slowly and weakly, and may die. Prompt treatment is necessary. Use penicillin or chlorine solutiontetracycline, or a 10 ppm oxytetracycline solution for bathing sick fish. Aquariums, fishing nets, tools, etc. should be soaked and disinfected with 0.1% formaldehyde solution.
3. Anchoriasis
Also known as needleworm disease; The head of the insect body burrows into the skin and muscles of the fish, and the insect body hangs on the fish body like a short needle. When the insect's body is removed, the iron anchor-shaped head can be seen. The affected area becomes inflamed, red, swollen, erythemic and necrotic and is easily invaded by bacteria. Sick fish are irritable, have a weakened appetite and become emaciated.
4. Filariasis
Filariasis parasitizes the skin and gills. There is a layer of milky white mucus on the gills and body surface; it is cloud-shaped, that is why it is also called; cloud diseasewhite people. The gill filaments are light red and the skin is inflamed and dull. Sick fish have difficulty breathing, swim slowly, gradually lose weight, and often die in large numbers

Based on your own practice, check the information online. , reading reference books, etc., we have summarized the following reasons and solutions for the death of a goldfish for the first time. The method hopes to be useful to you
Reason 1. The problem of white spot disease. First-time raised goldfish are prone to white spot disease when water temperatures change significantly. After the students brought the goldfish home, they directly put it into the aquarium, which caused the fish to "move" drastically in the body of water. temperature differences. So there was an outbreak of white spot disease. White spot disease is also known as melon worm disease, and melon worms are found in natural bodies of water. The surface of the diseased fish will appear covered in a white film and the fish will swim slowly, become lethargic and eventually die in large numbers. There are two points to pay attention to to prevent white spot disease: First, the newly purchased fish should pass through the water (let the fish gradually adapt to the water temperature of the aquarium) . The second is to avoid excessive changes in water temperature during feeding. To treat fish with this type of disease, you can soak the fish in a solution containing 1 tablet of 50 ml of nitrofuracil per kilogram of water for 1 week or soak the fish in a solution of 1:40,000 to 3/10 million mercury acetate for 1 week. 30 minutes. Or slowly increase the water temperature to 30 degrees Celsius (small pumelon pods cannot reproduce in water at 30 degrees Celsius). It turns out that the water in the aquarium should also be completely changed.
Reason 2. Use tap water to change the goldfish water directly. Some people who keep goldfish for the first time may immediately replace the water in the glass tank with tap water when they find that the water in the glass tank where their goldfish is kept is very dirty and trouble. At this time, the "bleaching powder" in tap water will affect the health of the fish and cause the goldfish to die. To solve such problems, you need to learn water changing techniques. We can add Yulebao (sodium thiosulfate) to tap water, which is a chemical method of water conditioning. We can also filter or continuously dry tap water, which constitutes physical conditioning.and water.
Reason 3. Poor management, overabundance of goldfish and deterioration of water quality. Some people do not take much care of the goldfish after purchasing it; others feed it vigorously after purchasing it. Both of the above situations can cause water quality to deteriorate and lead to the death of goldfish. Conditions must be created to circulate and filter the water (as shown in the image on the right) and feed it appropriately to prevent water quality from deteriorating.
Of course you can, but you have to be diligent. Always check if the water quality is clear, as fish often defecate and some cannot be caught with a fishing net. You can pour the fish into an aquarium or sink with the water, save the fish's droppings, and then put them back in. the aquarium. Do not overfeed the fish. Frequently, feed them once around 9 a.m. and once at 4 p.m. Take a basin of tap water (preferably solar water, I use solar water) and put it in the sun for three or two days. If the fish's water becomes dirty, change the water in it. Don't change all of the fish's water. Just replace it with half. Unless it is extremely dirty, the fish will rub against the wall in the water and swim away quickly. When it stops moving, change all the water. If the water has just been changed and is a little muddy. Simply put as much salt as half a watermelon seed to kill bacteria. The fish needs to be exposed to sunlight, so enjoy it for an hour or two each day. Good for fish. In addition, when changing the water, there will be a layer of lint, which is dust, on the surface of the sun-dried water. The top layer must be evacuated. The above is mWe have aquarium breeding experience, I hope you can adopt it.
