The adult size of razor turtles is between 15 and 17 cm. They are common ornamental turtles, but their adult size is not very large. If the breeding environment is comfortable and adequate food and nutrition can be guaranteed, their size will be relatively large, but the longest length will not exceed 20 cm. If there is not enough room for breeding, and they often get sick in childhood, they will develop slower and become smaller in adulthood.

If breeders want to make razor turtles grow bigger, it is best to prepare a larger container for them, so as to ensure that they have enough room to move. In addition, they develop at the fastest rate in the first year after birth, so breeders need to feed them more high-nutrition foods, which can also promote their growth and development.

Razor turtles need to mature after adulthood, and how long they can reproduce depends on the feeding method and gender. Generally speaking, normally raised razor turtles can mature about 5 years after birth. If the feeding method is improper, the mature ones will grow a little. In addition, the maturity time of razor turtles of different genders is also different. Generally speaking, the maturity time of female turtles will be shorter, which will take about 4 years, while that of male turtles will take more than 5 years.
