I purchased a cowrie snail from the LFS a few months ago, very cool snail if you have never had one. I noticed it was grazing on my green star polyps which I didn't really mind at first until he ate most of it and then moved on to one of my new zoanthid frags, he ate all 8 polyps. the cowrie found a new home in my sump and I learned the LFS doesn't always know exactly what there livestock is because there are a few types of cowries that are reef safe. Just wondering if anyone else has expereinced this with a cowrie snail. Also lets here stories about things LFS has told you that has ended in bad results and also what the LFS said when you told them about there bad advice.
