Ok guys thanks for the answers. It was just worrying to me that my gecko that I've had for almost a year now isn't the same size than this supposed 6 month old gecko I got from a show. Also I've only seen him shed his skin once, and also my brother's girlfriend got the same age gecko as my own at the same time and her own gecko is noticeably bigger. I just always look forward to my pets becoming adults, so I always worry if they are at the size they should be or whatever.
