Dead Live Rock

[asylumdown]

I would also just caution that you make sure everything on the rock is truly dead. Was it stored dry? Aiptasia would be the perfect aquarium pets of they weren't hideous, sociopathic little serial killers. You would be shocked at what sort of conditions they can survive. I've had them survive submerging a rock in a pot of boiling water because I didn't leave it in long enough for the dead centre of the rock to reach boiling temp. Every last thing on the rock was nuked, but within 24 hours of going back in the tank, a mid-adult nem was poking it's head out from one of the holes. If the rock has remained damp at all, I would either leave it outside in the sun for a few days, or pop those suckers in the oven on low for an hour or two.
