theo is a red eared slider and his shell recently became discolored and looks flakey and dry. i also found mushy yellow stuff in his tank
These symptoms may suggest shell rot, a common issue in turtles that can result from poor water quality, inadequate UVB light, or nutritional deficiencies.
First, it's crucial to improve the water quality in Theo's tank. Make sure the tank is kept clean by changing the water regularly and using a reliable filtration system. Dirty water can harbor bacteria that contribute to shell rot.
Next, ensure that Theo has access to UVB light for about 10-12 hours each day. UVB light is essential for calcium metabolism and overall shell health.
For topical treatment, gently clean the affected areas of Theo's shell with a soft brush and apply a diluted iodine solution or an antibacterial ointment. Allow the shell to dry completely before placing Theo back in the water.
It's also important to monitor Theo's behavior and shell condition closely. If the discoloration and flakiness persist or worsen, it is essential to consult a veterinarian who specializes in reptiles.
