Ink is a physiological phenomenon of tortoise, usually due to sex hormones and environmental effects, this variation can not be stable inheritance.When it occurs ink, its skin, tortoise shell and eyes will gradually turn black, this situation belongs to full ink, there are also half ink, only the skin and eyes will change color, but the back and plastron still retain the original color.
1, choose the right sex: not all tortoises will ink, only the male will, the female is impossible to ink.Because the ink is mainly related to the secretion of male hormones, so as long as the male turtle for a long time will be ink, but because of the different levels of hormone secretion, the degree of ink is not the same.
2. Natural hibernation: If you want to make the grass turtle more quickly, you'd better let it hibernate naturally in winter.Hibernation is not necessary for turtles, but through hibernation can accelerate its sexual maturity, but also stimulate it to breed, so that hormone secretion will increase, the same process of ink will also accelerate.
3, Proper light: Ink is not created by living in a dark environment, on the contrary, living in a dark environment for a long time is not conducive to its development, and adequate light can not only make it more healthy, but also accelerate metabolism, so that it can grow faster, thereby increasing the speed of ink.
