Greetings. I recently put a small pond in my tortoise enclosure. I have one Burmese mountain tortoise which spends almost all of his time in the pond including night times. He otherwise seems healthy and he comes out to eat. He usually sleeps in the pond. All the other tortoises occasionally take a dip or a soak. Is this bad for my tortoise? I know that this variety of tortoise likes the water but this sort of weirds me out. Thanks!
