Before shelling of Brazilian tortoise, the gap of their carapace shield will become larger and larger, which is an obvious sign and is also for the convenience of shelling of Brazilian tortoise. Before shelling, the shield on their carapace will turn white, and a white film will fall off. This kind of film will affect the water quality, so the breeder needs to fish out or change the water in time. In addition, before shelling, the appetite of Brazilian tortoises will also be affected to some extent. Before shelling, their appetite will decrease, and some will stop eating. Moreover, their activity will be reduced, and some Brazilian tortoises will curl up in a corner and be inactive.

1. Water quality is clean: shelling Brazilian tortoises does not happen overnight, they fall off little by little. The shelled carapace will pollute the water quality, so it is best for breeders to change the water every day when they shell, so as to ensure the water quality is clean. However, the amount of water change should not be too large, and half of it should be changed at most every time. In addition, if the shell falls off in water, it needs to be fished out in time.

2. Adequate food: Brazilian tortoises need more nutrition when shelling, and breeders need to feed them a lot of food, so as to ensure that they have enough energy when shelling. Although they should be fed a lot of food, we should also pay attention to the diversity of food, and we should not only feed a single food to ensure adequate nutrition.
