your best bet is to get them from someone here if you can. They will be a quarter to half the cost. 
Did you get the shrimp tank going? I'm looking for a few RCS. I went to about 6 LFS over the last few days and came up empty.Hey all,
Just joined this forum. I wanted to also let you know that I'm going to be setting up 2 shrimp tanks. I would more than happily be willing to ship some over to you guys in the coming months once I get them breeding and such.:icon_cool
