The schedule is for dusting, Don't put d3 in the tank. Just pure calcium. You don't want them eating d3 all the time. So always just keep pure calcium in the tank.

They can eat a variety of different insects.

Crickets, Mealworms, Adults can eat superworms, butter worms, silkworms and roaches.

Silkworms being the healthiest feeder but also the hardest to maintain and the most expensive.

I use mealworms as their staple diet, cause I breed them and never have to buy them food. Then I feed crickets or supers to mix it up a little.

They can also eat waxworms but those are really high in fat and aren't good for them to eat as a staple. They do love them. So I use that for treats. Or if I get a rescue thats really skinny I will use those to fatten them up.

They don't come gutloaded, they are empty shells when you get them. I use a mix of wheat bran, dry oatmeal and some multivitamin mixed in for the mealies, this will work for crickets also. Then just provide thin apple slices for moisture for the insects. you can also get some awesome gutload at www.cricketfood.com. Don't buy commerical gotload like flukers that stuff is a waste of money.
