I have Zoas do this occasionally too, but they are always new frags. I always put it down to them being some of the more finicky Zoas like Magicians, and Blue Steels. Plus my Filefish was eating them when he was in there.

Very nice setup ZoaElite

You may have a case of zoa pox... it's like chicken pox but for zoas. Palys seem somewhat unaffected by zoa pox. If your zoas are closing up and stay closed and you see very small white spots not many but a couple here and there you probly have zoa pox.

Also as for dipping your zoas, I use flatworm exit. It kills everything not just flat worms. It will get rid of nudis,bristle worms, flatworms, those pesky little white 5 leg starfish etc etc without harming the zoas. When I buy a zoa frag etc I just add a few drops of FE to the water in the bag I bought the zoas in and give it anywhere from 10-20 minutes. Give it a rinse of some tank water and Bam! all is well. As for nudi eggs I use an old toothbrush as it grabs the whole egg sack in one swoop.

Anyhow hope you get it sorted out.

No white spots anywhere, pretty positive of that. Good tip on the flat worm exit though!

bristle worms are narrower and pointier and have significantly less bristles than the broader and flatter fireworm....they do have bristles right? so not a eucinid worm?(SP?)
