The body length of red-eared tortoises in adulthood is mostly between 20-30 cm, but how big they can grow is affected by many factors. If there is not enough room for breeding, their body length will not reach the normal standard. If the food fed is not nutritious enough or the food is scarce, their body shape will not develop very well. In addition, red-eared tortoises often get sick in their infancy, which will also affect their growth and development.

In addition to the influence of feeding environment, gender also affects their body shape. Under normal feeding, the weight of female turtles can reach 1000-2000 grams, while the weight of male turtles is generally about 500 grams, and rarely exceeds 500 grams.

If breeders want to make them grow bigger, it is best to ensure that their living environment is comfortable and their food is sufficient. It is best to sterilize them regularly, which can effectively prevent diseases.

The life span of red-eared tortoise is not very long, generally about 15-25 years. If it is a captive red-eared tortoise, its life span is mostly about 20 years. If raised properly, the life span may be longer. But how long you can live depends on the breeding environment. If they live in a poor environment, their life span cannot reach more than 15 years. If the breeding environment is proper, it is possible to live for more than 25 years.

Wild red-eared tortoises live longer, about 25 years, and some can live to more than 25 years.
