I would like to know the fish that are in there--IMO corals aren't strain on the biomass of the tank---but in a new tank they certainly could be throwing off the water chemistry--alkalinity,calcium and pH--which in turn will affect each others health.

This coral need food. And the amount they need will cause more trouble then the coral. Coral do put less load but whats the load to coral rate. Then they what if factor. What if he didnt add so many would he still have this same problem. Adding this many so soon is taking a risk and would be great to eliminate it as a problem.

No no no the tank has been set up since Dec 21 07. The bulbs are 2 months old. That would make the tank right at four months. 40 lbs of the rock came from my 29 when I up graded.

I will update tomorrow on how things look. I did a 20gal WC and the color came back in all the polyps that didn't look good. I will see how they look tomorrow. I belive that the problem is with the
mag buffer I was using. I didn't use it for this WC and they already look better.

Yea. They are looking way better today. I think it was the mag additive. Thats the only thing I changed and they are turning around.

IME with zoanthids, there are 4 primary things that cause a colony to melt down.
1. Low nutrients. A sterile or low nutrient system can cause a colony to shut down. Be sure you are feeding the system enough and keeping some level of dissolved nutrients in the system. Most zoanthids do not show a feeding response, so target feeding is fruitless.
2. Predators. Critters like Nudi's, Spiders, Sundial Snails (these suckers are sneaky and can hide in crevices), coral eating fish, etc, can terrorize zoa colonies.
3. Allelopathy. Chemical warfare is a definite issue for zoanthid colonies.......Inter-species wars and from other corals. Look to see what is "upstream" from the colony. If there is a robust and happy colony nearby or directly upstream, that is a likely culprit (perhaps your new goniopora).
4. Lighting. I have come to find that zoanthids can be very finicky when it comes to lighting. Some love the brightest light you can provide. Others love the lower lighting of PC's or a partially shaded spot. It is hard to know if the species you have came from a deepwater area or otherwise. If they are aquacultured, as the seller what lighting they were raised in.
I have had the unfortunate experience of a colony shutting down on several occasions. I have been able to save about 75-80% of them. Sometimes pulling the colony and dipping in freshwater or iodine is the cure. Other times, it is necessary to relocate the colony to a new spot in the tank or to a completely different tank. On a couple of occasions, I have fragged/cut of the decaying section and a few good ones for the sake of the colony.
Be objective and diagnose the issue. Act now and quickly IMO/E. Here is an essay that I wrote a while back.....I hope all this info helps:
