Are These My Tigger Pods?

[Richardsonic]

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.

Looks like pineapple sponges. Good filter feeders

Great. I thought they were more sponge-like but the way they just showed up everywhere and all at once surprised me. Thanks.
