Zoa pest

[umbis]

Any idea what this is? It white, and kinda moss-like. It will peel off in chunks, usually without damaging the coral. So far it's infesting 2 small colonies. The zoas looked stressed and don't open much. Sorry about the bad photo.

sponge, i had this happen.. just take the frag out of water and shake the water off and let it sit in the air for 10 minutes.. then drop it back in.. the sponge will die, the zoos will never know the difference.

Cool, thanks. I had a couple with pineapple sponges on them, but they're easy to pull off.

Heres a thread i started a while ago showing the sponges on my zoa colony up close. i didnt ever update it with my solution.. but does it kind of look like that?

It's very similar (but different). I would say mine have more branches, but they seem to spread the same way. Seeing as there are so many species of sponge, I'd say you're bang on. And yeah, fresh water dipping didn't do anything. Thanks.

I use the little dentist tools that come in the big screwdriver set from Canadian tire, works good for getting between polyps to scrape sponge off.
