Chinese Water Dragon Eating Habits

Question
We recently got a Chinese Water Dragon and initially he would eat the superworms and wax worms but now he is only eating crickets, we don't want to only feed him crickets because we've read they aren't nutritionally sound food but since that is all he'll eat we don't want to deprive him either. He's about 16" and since we've had him (about 3 weeks) his color has come in beautifully and he is very personable and likes to run around or be held. I'm just worried that he's not going to be very healthy if he's only eating crickets, he will eat about 6 or 7 a day.
Do you have any advice or info on how to expand his diet?

Answer
Acctualy crickets make a better diet then super worm or wax worms a staple diet of crickets or Silkworms is recomended for most insect eatting lizards you can ofer a super or wax worm every now and then but not too often. Dust the crickets with vitamin or calcium powders as well.
