Borderjumper, 7 Firefish together sounds like a pretty sweet tank. Would you mind posting a full tank shot?
As for "healthy fish rarely die in strange ways", that's something that I disagree with. Alot of reefers on the board have flourishing tanks and to say that there's no way a healthy fish could be killed and eaten by a plate coral/anemone/paly is kind of misleading.
I think there's more than just the general "health" of the fish that decides the outcome.
