I know they are better left in the ocean. My lfs
had special ordered it for a guy the couldnt pay once it came in. So I got it for 5 bucks. It was originally 30, but I had store credit. This was a frag that came from some "expert" in australia. He said it was never out of water. My guy put bag in water to remove it and I put bag in my tank to pull it out. So no, I dont think it was ever exposed to air.
The wierd thing is, I cant really tell which end is up. I cant tell how this thing was placed when it was at the fraggers.
