What is this on new GSP colony?

[Fishy Guy]

I picked up a small GSP colony attached to some Marco rock from a local reefer. While doing a dip I discovered about a dozen or so of these around the rock and coral?

Worried that this is something like aiptasia (though not sure if they can close up like that) or another sort of unwelcome hitchhiker.

I currently have the rock in a holding container and won’t add it to the tank until I can get some confirmation.

Pineapple sponges. Harmless, but scrape them off so they don't annoy your coral

Lol. Not at all. We all have questions. I thought my first pods were like a roach infestation.

My wife calls the pods water fleas ha.
