I recently started a colony (new to the roaches to), you wont regret it. They dont smell, and are so easy! they've been in the same container for over a month without cleaning and still just smells like coconut fiber!
They are pretty slow and cant climb so you dont have to worry about escapees like crickets
Just feed them, and keep them warm (like 90-95)
i started with just 100 mixed mediums about a month ago just to try it out and i haven't been disappointing! im starting to see little babies in there now!
watch the classifieds on here many people trying to thin the herd
