It’s more complicated for you in Europe. However, I learned that bimacs were sold to European research labs and edcational institutions, as they are here. The problem is, they aren’t sold to individuals as pets.
O. bimaculoides is a very hardy species and travels well - the problem is getting one.
So guess what, there ist a departement of zoology of a university here that might be interested. Anyone here has a contact where they could go to?
