Your guy looks very beautiful but are you sure he is 220 grams? He looks to be maybe 150-180. He is very large never the less and looks great! Looks like you are doing a really good job with him!
Can we see some pics of your giant? Imagine what a beauty a large Nosy Be must Be. Mine grew up to be maybe 180-190 grams in his prime.... As he grew to be 7.5 years old he shrinked down to 140-150 grams
