If you suspect that your red-eared slider may have a respiratory infection, schedule an appointment with an experienced reptile veterinarian. They will likely take x-rays to examine the lungs and antibiotics to clear out the infection.
Meanwhile, double-check the basking temperature, as low temperatures are notorious for causing respiratory infections. While you’re at it, check what kind of heating you’re using. For best results, you should be using a halogen heat bulb, as halogens produce the highest quality heating.
