What reason is guppy blackens all over suddenly to die next? How to treat?

There are many reasons that can cause the whole body of guppy to turn black and die. To sum up, it can be roughly divided into four categories: deterioration of water quality, sudden change of water temperature, infection of bacteria and microorganisms, and violent contact. In view of the above four reasons, we can take four ways to solve them, namely, adjusting water quality, stabilizing water temperature, sterilizing and deinsectizing, and providing a quiet environment for their rest. We should take corresponding measures to solve the problem according to the cause of the disease, and do not treat it at random, so as not to cause the deterioration of the situation.

1. Deterioration

of water quality 1. Reasons: Although guppies are more tolerant to the living environment, the deterioration of water quality will still seriously affect their healthy growth. For example, if the water is not changed in time, the concentration of nitrous acid in the water body is too high, and the water pollution caused by excessive feeding can cause damage to the guppy, and cause the body of the guppy to turn black or even die.

2. Treatment method: It is necessary to keep the fish tank clean and change the water regularly. After the onset of the disease, the water should be changed in time and the water quality should be kept stable.

2. Sudden change

of water temperature 1. Reason: Guppy is sensitive to the change of water temperature. As a tropical fish, the favorite water temperature of guppy is 22-24 ℃. When the water temperature changes greatly in a short time, it will cause the metabolism of guppies to decrease, refuse to eat, and eventually appear the phenomenon of blackening and death of fish.

2. Treatment method: When feeding, keep the water temperature between 22 and 24 degrees Celsius and keep it constant. If the water temperature is not easy to control, it can be adjusted by the heating rod in the tank.

3. Suffering from diseases

1. Cause: The newly added fish in the fish tank is diseased. Or the presence of parasites in the water causes guppy infections, harmful microbial infections, or gastroenteritis. Can cause the body of guppies to turn black and die.

2. Treatment method: At this time, in addition to timely change of water to isolate the sick fish, the fish tank should also be disinfected, and the guppy should be treated with drugs. For example, the Black Death can be sterilized with yellow powder and increased light. If it is enteritis, you can feed the bait with oxytetracycline.

4. Violent contact

1. Cause: Too much violence when changing water or transferring guppies can cause damage to guppies and easily lead to blackening and death of their bodies.

2. How to deal with them: When transferring them, the action should be gentle so as not to hurt them. After getting them, the wound should be disinfected in time.
