Yh thats exactly what i thought. The petshop i got him from told me he was about 4months and he was about 1/2 an inch then, but i have also found out that he was hugely malnurished when i got him as all they were feeding him was a pinkie mouse once a week!! Since i have had him he has grown loads, i offer him food every night, the problem is my other half hates crickets so he was eating gut loaded locusts and dubias with every 2 feeds being dusted with a calcium sup inc d3. Thats why i want to get him onto the worms as iv heard nutritionally they are the best thing for him.
But he eats as much as he will take in a 15 min period
