Generally speaking, the size of the grass turtle is different depending on the sex. Generally speaking, the size of the female turtle is larger than that of the male turtle. Under normal feeding conditions, the longest female turtle can grow to about 28 centimeters, but the average is about 20 centimeters, and the heaviest weight can reach three kilograms. The male turtle is smaller, the longest can reach 15 centimeters, and the weight is about one kilogram. The reason for their different sizes is mainly genetic, and they take about five to nine years to really grow up and mature.
Generally, the grass turtle can lay eggs after being raised for five years. So if they reach the reproductive conditions as a sign of growth, they can generally carry out reproductive behavior in about five years, and from a physiological point of view, they can be regarded as adult turtles. But can really grow to about 20 centimeters of grass turtles, probably need 89 years of time, at this time from the size point of view is to reach the standard of adult turtles. But in the process of grass turtle growth, if you want it to grow rapidly, you need to feed carefully, such as supplementing nutritious bait, so that the turtle has enough space to move, or even more in the sun, can also promote its growth and development. However, it is not advisable to blindly pursue the growth rate, and it is better to breed according to the natural law.
