So i have had Bandit for almost 2 months now. I got her December 19th, 2014. The owner of the pet store told me that the beardie was about 2 months old when I bought her. I weighed her and measured her today.
Weight: 0.9 oz. or 27 grams
Length: 7.6 inches (Including tail)
She should be approaching 4 months now, and from what I have seen, she is very small. I dont know if the people at the store got her age wrong, but she does not seem that young.
She show her weight very much, if I do say so myself. we had an issue a few weeks back, but that is resolved. she was very skinny then, but now she is gorging herself with crickets and is FAT.
They all grow at different rates so it's hard to say for sure. If she has been eating a lot lately, she may be getting ready for a growth spurt which will close the gap pretty quickly. Young ones who eat a lot and look fat usually turn that around into more dragon pretty quickly. Keep offering her plenty of food and she'll be 400g before you know it =)
