1, illumination: sunlight plays a very important role in turtle's hair color. Adequate illumination can not only provide turtles with heat and promote the absorption of calcium, but also strengthen the deposition of pigments in the body and promote hair color. Adequate light can promote the inking of male grass turtles, and turtles that often bask in the back can also be more beautiful in shape and color.

2. Food: The healthy growth of turtles is inseparable from adequate food. The food should be rich and balanced. Feeding a single food for a long time will inevitably lead to nutritional imbalance. In addition to feeding turtle food, feeding shrimp, snails and other foods is more conducive to the growth and hair color of grass turtles.

3. Temperature: Temperature is very important to the inking of the male turtle. The inking of the male turtle is a manifestation of sexual maturity. If you want to completely inking, you must follow the natural growth law and let it hibernate normally. We have all seen the green house turtle, and its body color is pale, which is caused by long-term heating, too fast growth and insufficient pigment deposition in the body.

4, protection: ten ink and nine remnants ",it is very difficult to get a perfect ink turtle. Male grass turtles are more aggressive, especially after sexual maturity, and they have a strong sense of territory, so they are easily injured and disabled in the process of fighting and mating. We should do a good job in protecting the ink turtle and try to keep it isolated to avoid accidents.
