Don't be chicken guy

, damp shipping zoanthids, SPS, most softies, and even LPS has some very nice advantages.
The main advantage comes from the fact that we hobbyists are always loking to ship as cheap as possible, but keep the corals in great health along the way. When damp wrapped, which simply means take a papertowel (unscented and unprinted if possible) double it over in half. Then lay it across the top of the tank water, lift off, squeeze just a bit of the excess water out, then wrap the coral nice and snug.
Then use small bags (height doesnt matter, but 2-4 inch width seems to work for most frags) and drop the damp wrap and rubberband. Usually, you can get away with single bagging when using round plugs, ceramic disk, or matt only frags. Then take 2-3 of the small frag bags, and place inside a larger bag for extra protection and an additional moisture barrier.
This really helps on weight of package. Like twon mentioned, you can get almost a dozen frags safely shipped for 18.80 via USPS.
Also, an added, and possibly the biggest bonus, is that if the shipping company (any of them can mess up from time to time) delays the shipment an extra day, there is no water to foul which can quickly lead to the demise of the frags.
This is ESPECIALLY important with some of the "turn and burn" vendors in the zoanthid trade. I'm all for buying what catches your eye, but if you know the company just posted about a zoanthid/paly shipment arriving yesterday, and they are fragging and shipping the next day...heck even the next several weeks, it is in your best interest to ask for damp shipping. I watch so many vendors go down the tubes by not curing their zoanthid rocks prior to fragging and shipping....fungus amongus
You also get the protection of the moist towels so the frags don't get too beat up in their journey.
Another nice fact, is when they ask you about liquid, you can honestly say no as it's only damp and not in a liquid state
Great thread guys, have fun, ship damp, and enjoy the savings and incresed surviaval rate.
oh, as an aside, I realize some folks just feel more comfortable shipping with water. In that case, do as Marvin and others suggested and err on the side of less is better.
