He just ate a cricket! I also found out it's a boy, I walked in on it squeaking (I can't really call it croaking) on top of one of the others, who wasn't very happy about it! He's still a little nervous but as long as he's eating I'm not too worried. I'll just give him some time to get used to his new home. Thanks for all the help and we are going to get some smaller crickets in a few days (:
