My sav is atleast 4 month but isn't that big, I thought he's be quite a bit bigger, he's currently 23 cm from head to tail. He eats fine, dusted gut loaded crickets, odd bugs like silk worms,king worms and a two rat pinkies a week. He has some agression issues but he's a bluffer so like today when I needed to measure him he hissed,showed me his teeth and whipped his tail, hopefully this gets better as he ages.
