Sterbai cory missing fins?

[becrac16]

I have 3 sterbai cory in my 55 gal, with no really aggressive fish other than a tiny bristlenose who gets grumpy when feeding. I noticed today that one of my corys is missing their 'feet fins', the fins that they can prop themselves up on the gravel. I'm so confused, there is no (open) wounds. I'm not sure if he was just born without them, or if they got ripped off somehow?? I'm not too worried about it, just wondering if anyone has heard of this happening before.

Not really but as long as the fish is happy and healthy eating and stuf im sure there might not be anything to worried about. Just keep the water clean in case they did get ripped off to keep infection at bay.

Thanks; the fish is doing fine, eating and swimming normally. I noticed a while ago that he doesn't sit up as straight as the others but I think he's fine.
