I believe they are. I walked into a LFS today and saw a brown mushroom rock listed for $15 (plus 10% off sale). The 3 mushrooms on it were no big deal (they look green and not bad actually in my tank) but the rock was decent sized (around 2 lbs) and purple. On top of it was 10 polyps of what I think are Tubbs Blues. Dark brown skirt and nicely blue in the middle. So I call the guy over and ask if that rock is $15. He says it's not actually marked but he'll give it to me for $15 I told him I was really just interested in the zoa more then the rock. He bags it up and tells me the zoa must have just been sitting on the rock they fell off and are at the bottom of the bag. I get home and find out they are actually on the back of one of those annoying decorator crabs. Unfortunately for the crab I liked the zoas more then it and the last decorator that was in my tank cut off a lot of bam bams. So a few are open they look great I would have paid $13.50 just for these zoa:
