I just fed him 4 crickets. The lady at the local pet store said that her crickets are fed with calcium and that the calcium powder wasnt necessary. I'm planning on buying some of the multivitamin soon. I have a heating mat on the side (not inside), but its not on the very bottom of the side, I have it kinda in the middle above the coco substrate. Should i move it down? Also how well do i need to mist? Tonight I just misted enough to cover the whole tank once. I plan on re-filling his water bowl tomorrow. Anything else I need to worry about?

I appreciate the help, I really don't want to mess up! Thanks!
