The shell on the tortoise's tail a little soft indicates calcium deficiency. During the growth of turtles, calcium supplement is particularly important. Calcium deficiency is easy to get soft nail disease, which is very unfavorable to their development. In the daily feeding process, besides adding calcium to food, it is necessary to give it more sunshine. Sun exposure can promote the synthesis of some nutrients. Although calcium cannot be supplemented directly, it is very helpful for calcium absorption.

1. Strengthen light: The first step in treating soft nail disease is to strengthen light, because light can promote the synthesis of vitamin D and benefit calcium absorption. Usually, let it bask in the sun every day, and the time is usually in the early morning. At this time, the light is not strong, so don't bask in the sun at noon to prevent it from dehydrating. The sun time is not too long, generally half an hour a day.

2. Adjust the feed: To prevent turtles from soft nail disease, the simplest way is to choose some calcium-containing feeds, the most common of which is shrimp, dried shrimp skin. It should be noted that it must be chopped before feeding, which is too big to digest. And can't use salt, otherwise it will cause its body edema.

3, adding calcium powder: In addition to choosing calcium-supplemented feed, calcium powder can also be added to feed, and cuttlefish bone powder is commonly used, which is cheap and has no side effects.
