About 3-4 or one or two fuzzies. You dont want to just do rodents though but supplement with crickets dusted with a vitamin powder of some kind, mealworms and waxworms if it will eat them, fish (stay away from goldfish and other oily fish like herring, stick to minnows of some kind or maybe ocean perch). Stay away from human food like hotdogs and such. Chicken is ok just rinse it off first before feeding. Can also try beef hearts as a occasional treat.
