To see the age of Brazilian red-eared turtles, you need to turn them over first, let their abdominal nails face up, and then observe their abdominal spots. Usually, several concentric circles on the abdominal spots mean that they have grown for several years. Although turtles are the representative of longevity, the life span of Brazilian turtles is not particularly long, and they can usually live for about 30 years. The length of one-year-old turtles is usually 5-6 cm, and the length of adult turtles can reach 17 cm.

1. Feeding: If you want to make Brazilian tortoises live for a long time, you must first do a good job of feeding. As an omnivorous tortoise, Brazilian tortoise can eat a lot of things. When feeding, it should pay attention to the combination of meat and vegetables. Usually, it can feed more meat, but it should add vegetables regularly, and at the same time pay attention to calcium supplement, so as to avoid it suffering from soft shell disease due to calcium deficiency.

2. Temperature: As a temperature-changing animal, the Brazilian tortoise also has high requirements for temperature. It is best to keep the temperature between 20-30 ℃, so that it can move normally. If the temperature is too low, it will become inactive and will not eat. Too high a temperature will also affect its growth, usually not exceeding 35 ℃.

3. Sun-drying: In order to make the Brazilian tortoise grow healthily, it is usually allowed to sun its back. There are many benefits of basking in the back, which can not only promote digestion, but also play a role in sterilization, because turtles are soaked in water for a long time, and they are easy to have bacteria on their bodies, so as to avoid getting sick by basking in the sun for sterilization and disinfection.
