You have to be a Blaberus collector to really find them interesting (I kept them for more than eight years but gave the culture to a friend a year or so ago). They are notably bigger than a Discoid, are just as easy to rear but look pretty similar. People tend to upgrade to B. giganteus or B. craniifer because of the greater size and color difference.No one? Are they that rare in captivity or are they just undesirable in some way to culture?
