Don't know if you still have these, but of all the roaches listed on roachcrossing's site, these are the one species I disagree with his care advice on the most... For the majority of people besides Kyle, these do best when kept quite humid, and minimally to moderately ventilated. He recommends keeping them dry, but everyone I ever sold them to who followed that advice ended up with a bunch of dead nymphs in a short amount of time. Whereas if you keep them humid, they'll breed like pests, in which case the trouble is preventing overpopulation crashes, not in getting them to survive to adulthood. I do have a full caresheet for this species
here if you are interested.
