tortoise ink is the natural physiological phenomenon of male tortoise after sexual maturity. The specific performance is that the body color of the male grass turtle gradually changes from dark brown or dark green to black, and this color change is general. Ink phenomenon generally starts from the eyes, and then gradually spread to the whole body. And this phenomenon generally occurs in male turtles, female turtles are extremely rare. The time when the male tortoise appears is probably around the fifth year of its growth period, when the male tortoise has already reached the standard of adult tortoise.
Whether a grass turtle can develop a black turtle is mainly determined by two aspects, one is innate genes, and the other is acquired training. First of all, the phenomenon of ink is determined by hormones, although some tortoises are male, but also because of genetic problems can not appear ink phenomenon, so when buying tortoises, it is best to choose a larger and darker male tortoise; Secondly, acquired cultivation is also very important for the occurrence of ink phenomenon, after buying back grass turtles, more efforts need to be made in feeding and environment. The choice of feeding is mainly fish, shrimp, meat and other living bait. While the environment gives it space to move, it also needs to keep changing water once or twice a month, about one third or one quarter of each time. In fact, as long as carefully raised, can be cultivated ink turtles.
