FWS doesn't kill them, just "strengthens" the coral. Also, as far as lowering temps, this reduces the metabolic rate of corals and inhibits growth, meaning that if/when a coral is damaged, it's ability to heal itself is compromised. Not an option I would choose.
I'm hoping that on the small frag they came in on, that there was only 2 or 3 on that piece, and they were still there when I removed it. I counted 3. If there were 4, then I might have an issue, I might not. If one let loose into the water column, it's possible a fish would have eaten it. Fingers crossed.
