Update: Just took her out of the hide and she seemed to resent being woken up and was more active, so I set her on the PVC hide and handed her a cricket. She snapped it right up, including the end of my finger! I put three others in her food bowl and she dived right in, so that's good! Really strange thing is that green spot has migrated! :O It is now on the opposite side of her neck from where it was, and it is smaller and not as round, more oval-ish. Also I couldn't really see the cricket bite anymore (though I didn't have my glasses on, I'm far sighted and need readers). Wondering now if I should use the Melafix after all or just continue to observe her...?
