Measures: If heavy metal salt drugs are poisoned, water should be changed in time, and the water temperature should be raised in time to speed up the metabolism of fish and eliminate toxic substances in fish more quickly, but it depends on the situation. If the situation is serious, seek medical attention in time.
2. Water quality problems. Water quality problems can be divided into two aspects: one is the aging of water quality, and the other is the sudden change of water quality. The former is because the ammonia nitrogen in the water is too high, and the latter is because of the large seasonal temperature difference.
Measures: first change the water in the fish tank to see what the situation is, and at the same time disinfect the fish tank when changing the water to avoid leaving pathogenic bacteria and doing useless work, so as to give the goldfish a healthy and sterile environment. Secondly, after the diagnosis of the cause, targeted treatment can be carried out. For goldfish disinfection, you can use a light potassium permanganate solution bath. Generally, the medicinal bath time is about 15 minutes. Of course, the time of medicinal bath depends on the adaptation of goldfish during this period.
3, disease, the main cause of goldfish black spot disease is that when fishing and transporting goldfish, the fish is injured due to friction, and the skin of the fish is infected with mold spores after being injured by trauma or parasites, thus inducing black spot disease.
Measures: We should do a good job in the prevention of black spot disease in daily life, such as being careful when fishing and transporting, not hurting goldfish, and avoiding being infected by parasites and germs. At the same time, a small amount of salt can be put in the aquarium for stocking new fish to inhibit the occurrence of water mold, and attention should be paid to cleaning and disinfection when feeding live bait, which can also better keep the water clean, isolate the growth of water mold and prevent goldfish from being infected with black spot disease. If the goldfish is unfortunately infected with black spot disease, you can try to splash a mixture of 250g salt and 250g baking soda on the fish tank of100 * 55 * 45cm, which takes several days of medicated bath, and the treatment effect is very remarkable.
