The key to what I say is relative size of the anenome compared to the size of the tank its in, granted, if a 6 inch speciman died in a 10 gallon tank, the results would be disaster, however, if that same speciman was housed in a 75/100 gallon tank, chances are the natural filtration would be able to absorb most, if not all of the contaminants. this provided the tank was healthy, and well aged.
