Uh, I think you may have over reacted :?
Ick isn't to bad, but with sensitive fish I can see why you were worried. Are you sure there was no Copper in the bagged fish water, why would the cleaner shrimp die? Hm, I would think the fish died from all that stress. I also think that is a pretty harsh salinity change in such a short period of time.
This must suck Doug. That is a huge loss of nice livestock.
I hope the reef gets better soon, take care.
