Sponge on Zoas?

[nden]

Noticed this white stuff covering the stalks of one of my zoas. Sponge? Turkey basting them doesn't remove them, though plucking and softly scraping it off with my tweezers seem to work. How do I prevent it from coming back, if it does, and can it spread to any of my other frags?

Thanks

Those are pineapple sponges I wouldn't say they are a bad thing. If you take them out of the water they will melt away. They love low light areas

Its sponge. Typically harmless but some can suffocate polyps. I'd remove with tweezers.

A peroxide dip should also clear them up pretty easily.
