I've kept my extremely small colony of hissers for a little over 2 years. They are kept on peat moss with some paper towel tubes and vaseline smeared around the side so they can't climb out. My roaches are pampered in no shape or form, I throw food in there maybe once or twice a week. I work with crested geckos and other Rhac. species and the left over Crested Gecko Diet by Repashy is thrown into water bottle cap dishes in the roach's cage. They are licked clean by the next morning. I throw lettuce in every now and then, grapes, dog food cat food, even chicken layer pellets.
I just ordered my first colony of dubia roaches this week and should expect them next week. The hissers are slow producers, so I almost can never feed them to my herps. But the Dubias are supposed to be fast producers and very easy to care for.
I have also worked with stick insects in the past although I do not currently keep any. I kept mine at room temp in a 10 gallon tank and tons of branches and fake plants. Misted him in the morning, fed him romaine, apples, bananas, some native plants around here. I didn't purchase him though. At the time I was working in a pet store and in Jan. someone brought him in. If he was released he'd die of the freezing temps, so I took him in.
