Yes, it's like "cherry eye" in cats and dogs.Has anyone seen these eye symptoms before? Here is a photo of his underside and where he sits in his hide unless he is fully inside. He doesn't really like to hang out in the cooler side with the cork wood hide and leaves ever except to eat because that is where I place his food.
Here is the similar case:
Turtle has swallen red spot near eye
My red-eared slider has some red spot near left eye. It has this spot around month. During this period nothing has changed, but I'm worrying about some potential troubles. Has someone dealt with similar case? Any help appreciates
I suspect you'll need a vet prescription to get the drops. Adjust nighttime temperature first and see if it helps in a 3-4 days.
