The sloughing of the tissue would typically be due to a sting from another chalice or a serious parameter issue (that is, if the chalice has been in the tank for a while). Hard to say why this happened with the new chalice pictures above. This has never happened to me but I do have friends that have had this happen upon putting it into the tank. In their case, the water was really cold due to improper packaging. I know this isn't the case here as WWC knows how to package and all the others seem to be okay (I assume).
