All wild caught will cost alot, some species dont breed in captivity and only become available to us seasonal. If your looking for a whole seller but carry all of lapradie and endli varient and probably the ones that supplies wetspot and other lfs in the US, i suggest contact Toyin from rehobothaquatics. Most of us hardcore poly keeper buys from him, but they are expenssive for a first time keeper.
+1 for WC polys you wont find any better than toyin....hands down
