Loach w/ White Nose/Nostrils... Sick?

[Madding]

One of my two Zipper Loaches has a white mark on the front of its head (snout/nostril area). It isn't risen up like a growth, it seems more like discolored skin. Has anyone ever experienced this before, and if so, what can I do to help the little guy?

Thanks

Could be a scrap from digging, it'll heal faster with lots of clean water. Watch it though, bacteria or fungus could set in.

The problem seems to have cleared itself up -- the spot is already gone. I'm not sure what it was, as there's nothing white in my tank to rub off on the loach. Maybe just a scrape that healed over quickly. Oh well, case closed.
