I've had a frag of the wild Aussie Ice Fire that was pretty expensive and like everyone else said they're very sensitive. My LFS Your Reef gets them in all of the time, but I've seen about 50% of the colonies just RTN. Mine lasted a few months and one day without warning just RTN'd. I don't think I'm going to buy a wild piece again.
The Reeffarmers is a much hardier piece and I grew mine from a little 1/2" frag for about the last 7-8 months. It's finally going through its growth spirt because I moved it high under my 250 watt 14k Phoenix bulbs under high flow. It's only about 2" now, so it's not much to look at yet

I also have two frags of the SSC and I'm having better luck with keeping the color in the Ice Fire for some reason. The SSC's lose color in my tank and I'm finally getting them to start to color back up.
