Reptiles do not grow to the size tank they are in. If they are in too small a tank they will become ill and their growth can be stunted. Growth depends on care .... diet, heat, UVB, etc. Baby beardies typically grow VERY quickly. They can eat 50 or more correctly sized crickets per DAY. Also, intestinal parasites can greatly affect growth rates. I recommend all beardies be checked for these when first acquired, then yearly.
it is hard to tell the age of bearded dragons because the grow faster or slower depending on how much they eat, how active they are, and how big the tank is. i have seen bearded dragons only about 7 inches at a year old and i have seen bearded dragons about 12 inches in 9 months. i know this dose not help much, sorry.
