I am not sure how old he was when I got him from the pet store, but I assume he was a month or so old. I do feed him daily, I have put calcium in the tank, I dust his food with calcium+D3, I just today switched up his food he now eats mealworms and crickets, just for some variety, I use a UTH, I do not have an over the tank heater, His warm side temps usually range in the 90-95 are, it does have have its high days but not dangerously high. He is usually a hearty and active eater and never has problems pooping. Is it just to soon to physically see a difference in size? I thought everything was good but my cousin got one a few days after me, and his was about the same size. He is doing everything wrong, I mean sand, one hide not humid, no UTH, just throws in crickets and leaves them, no moist hide, not monitoring temps or humidity, and STILL his has grown signifigantly, where as I am trying to do everything I can to make the conditions in the tank good, and it just isn't working. P.S. before you guys say anything trust me I have told my cousin time and time again, printed him care guides, everything he just wont listen to me when I tell him what hes doing is wrong.
