I'm a Petsmart associate, and we got a new pair of corn hatchlings in about two weeks ago. One is perfectly fine, but the other, an albino, has been refusing to feed (first time that's happened in all the time I've worked there). Tonight was the first night I happened to be working when he was supposed to get fed, and when I pulled him out I noticed a small discoloration about an inch upwards of his vent. None of the scales are buckled in or protruding, it's just this gray spot about the size of a pencil eraser. Nor is the spot localized to a few specific scales, it seems to kind of fade in from the surrounding area. I was just wondering if this might be scale rot or some other aliment. I'll try to get pictures when I go in tomorrow if need be.
