About a month ago I dumped a bottle of Reef Nutrition's Tigger Pods in my sump and display. I thought they might be something live for my fish to eat. I just got home from a two week vacation and these guys are everywhere. Are they my Tigger pods? They look like they plant a foot and then extend a filter feeding fan. Not what I thought a pod would look like (but hey, maybe I have a limited imagination). Whatever they are, my fish aren't eating them. Thanks for any ID.
