No, it is not a Longnose.... ;-) Thank you for the concern, though... I've researched them a bit before I got these two... This one is the Orange File, a 4 inch beauty with a "horn", orange from head to toe... Does not eat yet, though. It ate only brine at the store. First night I found it sleeping on the filter intake... I don't have overlow or sump on the QT, just a simple small Penguin 250, with very small suction, so - no damage to the fish at all!!! They are a little crazy , those files... Both very docile, very easygoing - but a little wacky. They both sit on their noses (mouths) all the time.
There is a very small white spot on the tip of the Orange File's fin. The tip's integrity is broken, may be shipping trauma. It's very minor, a microscopic piece of the fin tip is missing. And there is the white spot. Fungi? Bacterial? I am not sure. I think to wait and see if it gets bigger.
