I know who you are talking about! I happend to go in there and see that rock too. I did however notice that it had epoxy left on it from ripped off corals.....let me take one guess where those corals are.....hmm maybe another tank in the store? HUGE sigh for that store and the way customer service there. I once went in looking for frag glue. I asked where that would be and she took me over to the aquarium silicone and said this will work just fine. I laughed pretty hard and said " so you want my coral to wave around and wait 24 hours for that to cure outside the tank?" needless to say i walked out that day.
