Good advice from Mike there... Karma Mike!
Also, you should know that any tissue damage heliofungia suffer will likely be the end of the coral. Combine that with the fact that if anyone in the transportation process picks it up by the sides then the tissue will tear, and you have a recipe for a tough coral to get a good specimen of. Make sure when you handle it, you do so by putting your palm under the flat part (bottom) of the coral.
Also, if it does die, leave it in the tank! Often, months later, hundreds of baby heliofungia may appear, seemingly from nowhere!
