I don't feed anything other than crickets and greens. Have been told my many breeders mealworms have a tendency to cause impaction. I don't know too much about other worms though.
Before a year crickets up to 3 times a day (I do 2) and green given in the morning and picked up by atleast 6 pm.
Once they get to adulthood it's switched, more greens and less crickets.
Greens are easy............Trader Joe's sells a prepackaged bag in the salad section. It has collards, mustard and spinach. Spinach is not a huge no no for them but is not good in large quantities, so I pick out as much of it as possible before I put it in a food processor.
