I will ask around and see if I can find you a hobbyist in your general area, or at least your country, lol. I really wouldn't trust PI, and I am not trying to be rude. Alot of the sulawesi shrimp just don't import well, having a greater than 50% die-off and they have very particular conditions. Nerites are awesome, I have several varieties, but they are not easy to import either as alot of transhippers simply "don't do snails" and most often y ou can find them but they are not yet acclimated to freshwater. They are worth it if you can find them, just make sure its a very well-seasoned tank (running a year or so) as they do not always take well to supplemental diets and may require you to grow supplemental algae.
