Please help me ID this loach!

There was a man selling all sorts of fish in buckets by the side of the walking path that is near my work, and I noticed that he had some loaches. He called them dojo loaches, but that's not really what they look like to me. I bought one, and I was wondering if anyone had any idea what it is? He caught it from a local river, so it's a native Japanese species I would assume.
I apologize for the picture quality, I had to use my phone.
