We have a bearded dragon that was born on 5/15/05 and weighs 88 grams now. It is about 13 inches from nose to tail tip. He is currently in a 15 gallon tank as that is what we were told to keep him in when we got him on 9/11/2005. I think he is too big for his current home, and I was never really told when to move him, only when he is bigger. Well he is a lot bigger now. LOL I eventually want to put him in a 90 gallon tank I have waiting for him, and I also have a 55 I can use. My question is, when will he be big enough for the 90 and can I go straight to the 90 from the 15 or does he need to grow more in the 55? Thanks for any help any one can give us.
