M. rhinoceros - definitely one of my favorite roaches. The first living examples I ever saw were at the Australian Museum (Sydney) in late 1996. Until that point, I'd never even heard of them. Later on during the same trip, I saw a few that were kept as pets by an entomologist I met in South Australia. He had collected them personally during a visit to Queensland. Good luck to all who are captive rearing them - would much like to see them become better established in the hobby.
