What could have caused this unexpected death? I found her in the water, limbs and head in swimming position, eyes clear and open.
Conditions:
Almost 3 years old. Housed with a male RES of same age & only slightly larger, but fed separately. Normal behavior w/exception of extreme basking for approx. 10 days prior to death. No loss of appetite and no visible signs of disease.
Discussion of possible causes may help new RES owners and will satisfy my need to understand.
Thank you.
