From my understanding P. imperator are a little larger/bulkier than cavimanus? I'm not a big time scorp keeper but I'd imagine you are correct, especially in the stronger department.Long ago, knew someone who kept 3 P. cavimanus with a lone P. imperator. Came home one day to a very fat P. imperator. I gather that they save more energy, and when push comes to shove, can shove harder/better/faster/stronger.
Agree. P Cavimanus is not a communal ot tolerant sp. I've tried keeping a pair together for breeding and ended up with one fat P.Cavimanus and no brood. I might try again in the future with hopefully better results. I have heard that it might be possible to keep a mating pair together if they are mature, but wouldn't mix sp.Echoing the above
I couldn't even keep P.cavimanus with P.cavimanus! they are very angry scorpions!
