The body length of a 30-year-old tortoise can only grow to 20-30 cm, because the maximum size of a tortoise can only grow to 30 cm, and even if they live to 30 years old, their body size will not change much. In addition, there are great differences between female tortoises and male tortoises. Male tortoises are generally relatively small, with a body length of about 20 cm in adulthood, while female tortoises are larger, with a body length of about 30 cm in adulthood.
2. How do Brazilian tortoises feed for a long time1. Water temperature: Brazilian tortoises can tolerate high temperature, but not low temperature, so breeders usually need to control the water temperature between 22-26 ℃. In this way, Brazilian tortoises can live in comfortable temperatures and live longer.
2. Water quality: Brazilian tortoises have strong adaptability and can accept various water quality, so breeders do not need to deliberately adjust the water quality for them. However, in the process of feeding, it is necessary to use trapped water to avoid chlorine affecting their health. It is necessary to change the water in time and clean up the garbage in the fish tank to ensure the clean water quality in the container.
3. Feeding: Brazilian tortoises are omnivorous animals, and breeders can feed them some animal feeds, such as lean meat, animal viscera, red worms, bumper shrimp and so on. Then with some plant feed, they can ensure adequate nutrition. In addition, it is necessary to add some vitamin E powder or antibiotics in spring and autumn, which can make them stronger.
