I was under the impression that death wasnt the cause for releasing the toxins, but rather trauma, ie. being picked on or sucked into a power head, etc.. its their defense mech.
A friend who owns a local reef shop has had poor specimens die in his display with no foul effects...inotherwords, death of natural causes may not cause it to release the toxin...tho you may want to remove the coarps as soon as possible.
I had one for a few months and it was really cool. I just couldnt sleep at night knowing what "could" happen. I traded it back to th LFS.
