is it that common to get a mantis shrimp when you order LR from liverocks.com?
That would depend on how much rock you order. I had one in my 40lb shipment. Others have had none, or 2 or 3. You have to spend a little time inspecting and perhaps even dipping the rock on arrival. I dipped mine in hypersaline water 1.035 for a minute and flushed a few crabs out. I suspected two DEEP holes, into which I dripped some club soda - 3 bristle worms came out. I didn't get all of the crabs, though. There is a VERY HAIRY one in one hole, and a red one in another.
