Hi, I kept tarantulas and now would like to add some scorps. I have been offered species from South Africa, Opisthoptalmus is the one I like most, than I would say Opisthacanthus or Hadogenes sp. Not exactlly sure, do you think, that I should just pick what aesthetically appeals to me most? Should I judge some different criterias yet? Ill be greatful for any help. I wont ask now about care and such up until I make the purschase. Thanks a lot for help, maybe you can add few notes about this species, so it would been easier for me to decide. Definitelly will pick one of these friend offers
