I am not a great fan of buying rock from an on line dealer who sends the rock to you via ups or fedx.The guy from this link actually meets the plane that comes from fiji and takes it to the airline that comes to your airport.Also you pay the freight directly to the airline(around a dollar a pound)so you dont get ripped off by the seller for a giant freight bill.By the time the rock gets to you it could be out of the water as little as 2 days and rarely more than 3 so its good and fresh.Whatever was on or in the rock on the reef (sans coral) will be in the box when you open it.That has been known to include live fish.Most of the pics of his rock were taken by customers when they opened the box at home.
