If there are white spots on the back of Brazilian turtle, you can brush them off with a toothbrush and pay attention to changing water at the same time. The reason why there are white spots is that there are water molds in the water, which will happen if you don't pay attention to changing water at ordinary times. Because Brazilian tortoises live in water, they can't live without water most of the time. They eat and excrete in the water, so the water is easy to break. It is best to change the water after feeding at ordinary times, and replace it all.

1. Dry culture: After water mold of Brazilian tortoise, dry culture should be carried out first. Don't soak it in water all the time, so as not to get worse. The main thing is that dry cultivation is not completely dehydrated, and most water turtles can't stay away from water for too long. They should be soaked several times a day for about half an hour each time, so that they can replenish water.

2, medication: Water mold is difficult to heal itself, and it still needs to be treated with medication. First of all, use poviodarone to smear all over the body, which can sterilize and disinfect. Then, aiming at the affected part, we should use drugs such as malachite green or Baiduobang, so that the affected part can recover slowly.

3. Prevention: It is troublesome to treat water mold, so the best way is to prevent it. First of all, we should avoid injuries to Brazilian tortoises, try not to mix tortoises, and don't have anything too hard and sharp in the feeding containers. Secondly, we should pay attention to the temperature, the ambient temperature should be above 20 ℃, and we should bask in the sun at ordinary times.
