He looks exactly like my veiled at 5 months old also. Here's a pic
Yours looks good to me maybe bit under weight but that will be due to him not eating as much.
Might have something to do with the worms u have fed him he might of really enjoyed them and is waiting till u give him them again...
Kate how long have u used nutribol for.
I was using that for abit but have now changed to exo terra calcium with d3 and without.
I seen every1 going on about these supplements so decided to change from nutribol.
