I went to a good pet store to buy crickets for the crew and one of the employees suggested starting a colony of feeder roaches. He said that they are much healthier than crickets and once the colony is established you won't ever have to make the trip to get crickets again. Does anyone know of good species to do this with? They will be used to feed emporers, one ~5 inches and the other two about 4ish. Also, what is a good setup? I have limited space, so probably a non-flying/non climbing species so I can keep them in a smallish container (and so the scorps can catch them).
