It's not a halloween hermit, at least not like the usual ones that come through the LFS. I suspect that it IS related to them, though. Typical Halloween hermits have broad orange and black/grey bands, whereas this guy has very thin orange and dark red bands with some white highlights here and there.
No idea what kind he really is, where he came from, etc. I got him from Premium Aquatics about two years ago. I was in picking up some snails and stuff, and they had just this one of them alone in a section of the display tank. He was like $4 or $6 or something.
