1. Water temperature: Brazilian tortoises have low requirements for the environment, and they can survive in the water temperature between 3-43 ℃. But the most suitable temperature for their growth is between 20 and 30 ℃. During artificial rearing, the water temperature can be kept between 20-30 ℃.

2. Water quality: Brazilian tortoises can tolerate poor water quality, but if they want to grow better, it is best to change water frequently to ensure clean water quality. If conditions permit, you can change water 1-2 times a week, and the amount of water changed each time should be controlled at half of the total amount of water.

3. Illumination: Although Brazilian tortoises live in water for a long time, they also prefer to bask in the sun. Breeders can build an amphibious environment for them when breeding, so that they can freely choose where to live.

Brazilian tortoises are omnivorous tortoises, and they are not picky about food. Young Brazilian tortoises can be fed some small fish, shrimp, loach, red worm, bread worm, lean meat, etc. These foods contain a lot of protein and fat, which can meet most of their daily nutrition needs.

When they mature, they can be fed more plant feeds, such as cabbage, rape, cucumber, apple, banana, grape and so on. These foods contain a lot of vitamins and trace elements, which can improve their immunity and resistance.

Brazilian tortoises can choose to feed them once a day in their infancy because they eat less in their infancy. When you are an adult, you can change it to feed once every 2-3 days.
