CGD not enough?

Hey guys, yesterday was the ETHS expo in Houston and I picked me up a pretty nice crestie! I asked the breeder how old it is approximately and she said 6 months. I freaked out because I have a crestie at home that I've had for 10 months now and it is nowhere near that size. So when I got home I went home and checked the temps in it's tub and it was at 72-73. I also feed him CGD every other day as well. I've heard that when you offer cresties CGD AND crickets(dusted or not), they tend to grow faster than being just fed CGD alone. So I moved my gecko to a warmer side of my room(in one of the drawer spaces of my snake rack) and bought some crickets for it to be fed 1-2 times a week. The temps are now 75-76 degrees in its tub. Could the slightly cold temps and not being fed crickets be the culprit of my undersized crested gecko?

Theres probably no specific reason your gecko is smaller... geckos are individuals like people and grow at different rates I got two babies back in February and both have been slow growers and only now the biggest of the two is around 8 grams and the smaller of the two around 5 grams..... I only have a couple of my rhacs that will actually eat crickets the others ignore them.72-73 degrees is perfectlly fine and well within their temperature range to be comfortable :D

Your temperatures sound fine to me. When you get a crested gecko that does enjoy eating insects they do seem to grow a lot faster than others in general. Since I bought my tailess male in July, he went from 12 grams to 20 in only a few months. I only feed him dusted insects once or twice a week and always have fresh CGD. Somehow he just grows like a weed. If your gecko is smaller than one you saw at a show I wouldn't stress out about it.

Make sure the heated rack keeps the temperatures low enough for your little one. Prolonged heat has been known to cause a lot of problems.

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.
