Advertisement So, I'm looking to buy a parabuthus sp, and I'd like a bit of advice. I'm not a first-time scorpion keeper, at all.. I own some H. spinifer, but also a young H. arizonensis and 2 Buthus occitanus. I'd like to know which species has the least potent venom, and if possible has the most solid colours, not something pale etc.. anything bright is ok: bright brown, yellow.. not black as there are only 2 species from what I remember, both of which are pretty potent.. So.. I hope you can help me out guys!
