If the situation is serious, it can be treated with drug immersion. 2、 Common diseases and treatment methods of red tailed crown fish 1. White spot disease: one of the common diseases of tropical fish. The source of this disease is a parasite called small melon worm. White spots appear on the body surface after the disease, and then it will slowly expand. Since this parasite can not survive in the environment of 30 ℃, it can be eliminated by heating appropriately. After that, it is necessary to change the water to avoid the recurrence of the disease.
2. Water mildew: water mildew is usually caused by fish body injury and fungus invasion. When the red tailed crown fish is sick, there will be white flocs on the surface of the fish, which is the mycelium. In addition to treating diseases by changing water, heating and adding salt, medicine bath can also be carried out, which is usually soaked with povidone.
3. Exophthalmos: if the red crowns are found to be convex and the surrounding areas are red and swollen, it will be replaced by exophthalmos. This is a disease with a low incidence rate but high mortality rate, and the treatment is extremely difficult. In the early stage of illness, you can use organic silver drops. If the situation is serious, you need to put penicillin into water for treatment. （GongWeiHuangGuanYuDeLeHuiYangZenMeBan，GongWeiHuangGuanYuDeChangJianBingJiZhiLiaoFangFaJieShao）
