I have shrimp, the problem is the the shrimp are cheap and the shipping is not. You would need to oay me as much as $75 in shipping if I send you 12 or 15 shrimp which I would not charge more than $2 each. I started with 10, added 5 for the blue dreams and have now sold about 250 to date. If magnum decides to stay local and not take my free shrimp offer and he pays the shipping, I have 10 or 12 blue davidi and some number of the red cherry as well. But I have mostly blues.
Btw- my group of the reds came to me abut 15 years ago and they are still thriving a bit too small 5.5 gal. tank. The blue are in a 15 gal.
i have never shipped shrimp but I have shipped plenty of fish. I do know how to ship shrimp. The key is to add something to the bag onto which they can grab. Not doing this tends to drive them crazy. When I bag them to sell at auctions I add a sprig of anubias, Java fern or long leaf Hygro to the bag for this purpose. Even a piece of floss might work. Anything not toxic and that they can grab onto will work.
Overall, it is probably cheaper to buy them locally if you can than to have to pay for overnight shipping. If you wait for warmer weather it is less risky and wont require a heat pack. Also if you are in NV and I in NY, that means overnight shipping is almost a must at this time of year.
