What are the differences between Scolopendra Subspinipes mutilans and S. Heros castaneiceps? They look similar, but how do they differ in size, temperment, care, etc? I'm just wondering, because I've got the opportunity to get a centipede and I like the look of those two species, but I'm not sure which one I want yet.

The first is much smaller and rarely exceeds 4-5" at maturity, it can be kept in groups but not with absolute safety. The second is far larger easily reaching 7" at maturity and it does not like company.

Thanks. That works out too, because I found a guy selling CB S. h. castaneiceps plings.
