Pac mans are really not meant to be handled. The toxins on our hands are more harmful to them than they are to us. They are eating machines, and watch your fingers while feeding. Haha. I recommend getting tongs to feed them. Feed them as much as they'll take in a 10 min period.

I wouldn't feed them to many pinkies, once a week at best.
