Okay, earlier as I was feeding my turtle Sora her lettuce, I noticed she was having "difficulties" eating it. She seemed to not be able to keep her body in a perpendicular position (the "normal" floating position) and was kind of flailing about with the lettuce in her mouth. I noticed her tail twitching and that her back legs were sort of "clicking" together by her tail. So this went on for a few minutes, and then I noticed a red opening near where her tail meets her shell and I was really confused, because I've never seen her do that before.
I was wondering, could this have been her Vagina(Cloaca) or her Anus? Is it supposed to open, or is this a sign of internal illness? or is it maybe a sign that she's gravid and needs to lay eggs?
I'm really not sure as to what this may be, as she's never done this before. She has all the essentials (filter,light,basking area,etc) and hasn't shown signs of illness(although I know turtles are notorious for hiding their sickness), so this comes as a surprise to me.
What do you think it could be?
Any help would be appreciated, Thanks
