I have some Zoas that I got about a few weeks ago and have looked great untill the last couple of days. Some of the heads open and some do not. What could be causeing this? Also can Bristle worms aggrevate the coral? When I feed my corals I notice about 5 bristle worms come out of it and around it. The coral is about the size of your fist. I will try to post a pic later.
Zoa problems

I had the same symptoms when I first got into the hobby. I also thought it was bristle worms, but I still have bristle worms and no longer have the problem. That was my first colony of zoa's and I never figured out what caused it (perhaps new tank yet), but I really don't see the bristles causing my current zoas any problems and they live in em. I'd do a dip and see if anything else falls off.

Give it a good dip. I "think" I see something on some of the Zoas that shouldn't be there. If I was a betting man, I'd say nudis.
I dipped it in Coral RX today and in Reef dip when I got it. Only seen a few bristleworms come off and some other thing that may have been a worm. It was tan color.
Edit:
What other corals will the nudis eat? Also do you think you se nudis in the pic? Thanks

Nudis are very small and hard to see. They usually look a lot like the coral that they eat and generally only eat one type of coral.
They will hang out on the stalk, on the skirts and on the rock around the Zoas. They normally blend in and some times you don't see them until they are big. By that time, you will have probably lost a few polyps.
Have you added anything new?

Its just my thought and I may be wrong but it looks like they might be reaching for light I was always told this was a sign that they may need to be moved further up but I could be wrong on this.
If it's nudibranchs, a quick dip in fresh RO should kill them.
The thing you said was a tan colour - can you be more specific?
I doubt it's the bristleworms -they usually don't harm healthy living things. Nudibranchs though - that's another story.

One of my colonies of Zoa's look just like that...but it also happens to be the place where my new longnose hawk (lovingly now named spiderfish...and yes I sing to it when it is rock hopping) has decided to perch...I also moved the colony to the floor of my aquarium...but turned up my AI's from 55% max to 75% max. I also did a coral Rx dip before placement as well. I just think the hawk is disturbing them.
The stalks on yours still look healthy...hope you figure it out!

I only have about 8 corals in the 65 gallon tank. It was one of the first corals I got and I dipped with seachem reef dip or something like that when I got it. How long should I wait to dip it again and should I do a coral rx dip or fresh RO dip?
So it turns out I think it was Pox. I decided to remove the colony totaly and also another small frag I picked up at the swap. The small frag was starting to look affected as well. I have one more small colony left in the tank and I hope it makes it. If they all die how long do I have to wait before I can get more Zoas and them not be affected by the pox that were in my tank before? Do the pox die off with no zoas in the tank?
