Zoanthid hitchhiker ID

Something appears to be growing around the base of my Rasta zoas. Looks like maybe some type of translucent sponge? It doesn’t seem to have caused any issues thus far. Thoughts? Anything to be worried about?

Yeah id try to remove that, you can use tweezers or toothbrush. The zoas look bothered by it

I might try that. I disturbed the zoas so they’d close and I could get a better pic. They’ve been opening and seem normal otherwise.
