I've never kept Hottentottas communually. However i have 2 6i Hottentotta Judaicus and 1 5i. Maybe once they're all grown i can give it a shot. But yeah I'd wait until they're adults before housing them togetherHottentotta hottentotta, I have kept them for a while you can never keep them together when they are young however from subadult on they're very communal will not fight and have never showed any signs of aggression towards one another I currently have three that I keep and A 5 by 5 gallon zilla critter cage. This is a very docile scorpion species even towards each other however they are hot so do not handle
As adults, they are perfectly fine together
At younger stages, they dont fare as well, and will be opportunistically cannibalistic. As with everything in nature, individuals in their actions, temperaments, etc will all differ, and while your two may do fine together, others may not. There is no absolute, and as others have stated, it is recommended to raise them separately.
