Im going to be picking up my Pacman Frog soon but before i buy everything i want to make sure a few questions i have are cleared up.

-Would the preferred feeding supplement be Repcal Calcium powder WITH d3?
-How often would i need to dust the food with it^?
-Is there anything else i could use as a staple diet instead of crickets? ANYTHING besides the dang crickets..lol

Any other advice or extra tips for the first few days i have him would be appreciated! This is going to be my first frog so i am excited but a little nervous.
