Hi i have a red eared slider about 4 mths old and he is spinnig in circles and flipping upside down does anybody know whats wrong with him???????????? :(

I've not heard of that problem before but it doesn't sound good. What kind of setup do you have him in as far as space, water depth, lighting, heat, etc.? What are you feeding? Perhaps he has a middle-ear infection or something else is wrong with his balance. Hopefully you can find information from someone with more experience with turtles than I have. A trip to the vet may be in order.
