I raise Hissers. I got intot hem, because I like unusual things as pets. Plus they are very easy to care for, don't bite or scratch you, don't die if dropped on the floor, don't die if you forget to feed or water them for a day or two, and they don't require any special care or a large cage.
I feed mostly carrots and spinach with the occasional apple as far as fruits and veggies go. I also feed rabbit pellets, dog or cat food, and chicken feed for the added nutrients and some dry feed. I use milk jug klids for my water. They are too shallow for drowning in and they rinse well. I have found that the watter isn't much needed as long as moist veggies are fed daily.
Try to avoid anything that will mold. Strawberries, bananas, things like that. Carrots and apples just dry up if not eaten right away, but those mold and smell.
I use a small critter keeper for my roaches. I taped toilet paper over the vents to keep the nymphs in the cage. I provide them with about four sections of an egg carton to hide in and a couple of small branches to climb on. I use toilet paper or paper towels for bedding. They are easy to clean and the nymphs don't get lost in them.
