Compared with other turtles, the growth rate of yellow-eared turtles is normal, and they can grow about 4-6 cm a year, but how big they can grow depends on factors such as the size of feeding space and feeding methods. Because yellow-eared turtles can adapt to poor environment and have high requirements on environment, the breeding environment has little influence on their growth speed.

If they are kept in a comfortable environment with plenty of food and space, they will grow much faster. If there is not enough room and food for breeding, their growth will slow down a lot.

Generally, yellow-eared turtles start mating from March to June every year, and start nesting from June to July every year. It takes about 3-5 years for yellow-eared turtles to mature, and how long they mature depends on the breeding environment and their own physique. Under normal circumstances, male turtles will mature faster, about 2-5 years. Female turtles will mature slowly, which takes about 3-5 years. However, yellow-eared turtles usually reproduce about one year after maturity. Because they are just mature and their organs are unstable, immediate reproduction may affect the quality of their offspring.
