alrha,
The crabs would eat the bubbles and it would pop, but then they continue eating any bubbles that grows out from that event. I've always found emerald crabs to be an iffy subject since none of mine ever touched them.
You can try using tweezers to pop the bubbles outside of the tank to minimize spore release into the tank.
As for the frags of the blue millepora, not to belabor the issue, I thought I was the second. Hmmm...I was the asian guy. I asked first and then paid with the $20. I got back 2 5's in return. The last guy (I believe the 3rd guy or could be the fourth) in fact got two frags for free. (My wife told me that he took one frag ( which I saw) and the second frag from the tank. ( the one that was dropped in)...not very nice in my opinion since how can you forget to pay?
Cali, were you the one right before Gary? I don't have a digital camera on hand and eventually will take a pic of it, but I'm pretty sure that the purple tip is the same one you're referring to. It was the baby brother of the huge purple tip on the left. It was situated way in the back and very unobtrusive. I asked Jeff if it was the same kind, and he indicated that it was.
To all, it was nice meeting you guys.
