1. Rotten armor disease 1. Reason: The shell of Brazilian tortoise becomes yellower and yellower, which may be caused by rot armor disease. In the middle stage of rot armor disease, the color of their carapace becomes yellower and yellower. The main causes of rot are poor water quality, alkaline water quality or bacterial infection.
2. Treatment: Breeders need to transfer them to new containers, and it is best to dry them if they have time. Then find the position of rotten skin, disinfect it with hydrogen peroxide first, and then apply chlortetracycline eye ointment on the affected part.
2. Lack of light1. Reason: The shells of tortoises are getting yellower and yellower. It is possible that they spend too little time in the sun, because sunlight also accelerates their pigmentation. If there is no light, the color will turn yellow.
2. Treatment: Breeders need to build a balcony for them, so that they can climb up and bask in the sun anytime and anywhere. It is also possible to transfer the breeding containers to the outside and then block out half of the sunlight, so as to ensure that they have enough sunlight.
3. Improper feeding1. Reason: The shell of Brazilian tortoise becomes yellower and yellower. It may also be due to unreasonable feeding. For example, when feeding at ordinary times, the amount of plant feed is small, which will lead to yellowing of their carapace.
2. Treatment: Breeders need to increase the feeding amount of plant feed, and it is best to choose some dark green vegetables for feeding. Because Brazilian tortoises live in water when they are in the wild, there are many green plants in the water, such as aquatic plants, algae and duckweed.
