I'm living in Indiana. I caught this snake in creek when I was fishing at Oakdele dam. I wonder if this is a water snake or what? I decided to keep him as my first snake pet. I don't know where to ask. This is my first post here. I've been googleing for an entire day and figured out it might be a northern water snake? or banded water snake? but I found that banded water snake is not in Indiana. So....please help me. I wonder if my setup is correct for this new mate? I found that many forum suggest not to use gravel as bedding. But since I found it in water, I figured that I should use semi-aqua setup? Is this snake exotic? How to take him out to change the bedding and water?

Thanks!
