Why does my red-eared slider tilt when floating? Is it normal?

One of the most common causes of lopsided swimming/floating in a water turtle is pathology of the lung. If it just occurred, we would be concerned about pneumonia. If this has been going on for years, I wonder if he could possibly have a collapsed lung or a mass on one side making his balance off. A vet may be able to x-ray your turtle to check for signs of disease that could be causing his issue.

Thanks for reaching out about Snappy. Sleeping is a sign of lethargy and illness, and a veterinary visit should be scheduled as soon as possible. Floating all the time is an indication of hyper-inflated lungs and possible respiratory infection. Systemic disease require systemic antibiotics, which a veterinarian can prescribe. Good luck.

This could be very normal for him as long as he is still eating normally! If he isn’t eating then I would have your vet look at him. You may consider making his basking platform a little bigger if you’re concerned he is having trouble staying on it. I hope this helps! Red eared slider have great little personalities!

If she seems bright and healthy I would not worry about this too much. Quite often turtles choose to spend most time in the water. Make sure there is no reason that she a is put off the dock, for example difficult to access, excessively lit or heated, cleanliness etc. If there is no husbandry reason it is simply her choice.

Check the water temperature and ambient temperature. Low temps can affect appetite and activity in reptiles. Keep the water between 24 C and 30 C. A basking spot out of the water should be 29 C to 31 C. UVB lighting should also be provided. Maintain water quality to prevent infections and feed an appropriate diet with vitamin and mineral supplementation. A vitamin A deficiency can cause swelling of the eyes. Repti-Turtle Eye Drops (by Zoo Med) can be used to help the eyes. Find it online or in the local pet store. Soak the little guy in a 50/50 mix of warm water and an electrolyte replacement beverage to maintain hydration. You can read more about care here: http://www.anapsid.org/reslider.html

Maintain pristine water quality and proper temperature. You can even bump water and ambient temps about 5 F to aid in recovery. Offer some freeze dried shrimp or krill to stimulate the appetite. Small bits of fresh beef heart may also get him eating. Other protein sources include feeder fish and nightcrawlers.

Turtles will bask in a variety of positions to maximize heat and UVB absorption. If she is behaving normally otherwise, there is likely no cause for concern. Monitor for lethargy, difficulty breathing, "gaping" (opening and closing mouth), blowing bubbles or discharge from the nose or mouth, decreased appetite or lopsided swimming. See your veterinarian or an experienced herp veterinarian if any of these symptoms develop.
