Mail Order Critters - How do they come packaged?

Hello everyone. Thanks to all of you who answered my earlier questions.
For my next question, I was wonder how mail order critters

arrive when you purchase them online? More specifically I am really curious
about how corals and anemones arrive. Are they attached

to something? In the case of anemones, how to you place them in the aquarium
without damaging its "foot"? Same for the corals (just

some general info. here because I understand that needs vary from one
organism to the next. It is going to be some time (month or two)

before I add any of the above mentioned animals. Any info. you can share
will be greatly appreciated.



On another note, I just ordered 40 lbs of live sand (using that to seed 20
lbs or so of "dead" sand. I also ordered 65 lbs. of Carribean live rock.
Things are moving along nicely.
