Common Illnesses of Red-Eared Sliders

Daily Care 📅 August 7, 2026 👁 2256

📝 Summary

Red-eared sliders face several common illnesses: white-eye disease (a white film from poor water), gastroenteritis (odd red-green stools), pneumonia (wheezing, head held high), skin rot, calcium deficiency (soft shell), shell rot, and colds. Most trace to water quality and temperature swings, and many respond to antibiotic soaks or ointments plus warmth and sunlight.

1 White-Eye Disease

Common in spring and autumn, mostly from poor water. Signs are eyes that will not open, eroded cornea and tissue around it, and a white film over the eye, which is clear and risky; untreated it can be fatal. Drop chloramphenicol or another anti-inflammatory eye solution into the eye once or twice daily.

2 Gastroenteritis

Usually from poor digestion: stale food or a big temperature swing in the tank. Stools turn abnormal, not just loose but reddish-brown or pale green. Sick turtles look vacant, dull, thin, unwilling to move, drink a lot, and have diarrhea. Soak the turtle 60 minutes in 300,000-unit erythromycin solution and mix oxytetracycline into the feed.

3 Pneumonia

More likely in summer and winter, especially with large temperature changes. Signs are nasal discharge, loud breathing, head held high, weak front and hind legs, and frequent panting. Dissolve two azithromycin dispersible tablets in the water and soak the turtle, changing the water every 12 hours, twice a day.

4 Skin Rot

Signs are sores and whitened skin. Clean the wound and apply chlortetracycline eye ointment.

5 Calcium Deficiency

The shell softens or deforms. Feed more fish and shrimp for calcium and give plenty of sunlight.

6 Shell Rot

The shell surface ulcers; severe cases form pits or expose muscle. Scrape away the rotten skin or shell, wipe the site with hydrogen peroxide, then dust potassium permanganate crystals directly on it.

7 Colds

The clear sign is a runny nose. Raise the water temperature and crush a little amoxicillin into the food.
