[JimSWreef]

Anyone know what the two brown things are growinge in my zoa it definitely opens and closes. So weird looking!

Can't see really well but if I were to venture a guess, I'd say that looks like hydroids.

It looks like a sponge, but is it making the Zoas close up

Sponges don't open and close.

Its not making them close. Zoas are extremely healthy... Just uad to take the picture righht when i turned my lights on because all my zoa polyps cover the brown thing. Ill try to take another pic.

I believe those are syphonophores.... commonly called sea squirts. Harmless, but can spread readily, given the right conditions. They actually help with water quality as they are filter feeders. I'D leave em alone unless they bother you aesthetically.
