Zoas turning brown
I have a colony of radioactive dragon eyes and green bay packers. i ve noticed today that some of the polyps are closed and turning brown... What can this be? Nothing is close to them and i fragged off some of them a while back and those are doing fine. Only some in the colony are turning brown not all. They are ay about mid level in my tank but kind of under the center brace on my 75 gallon so they are not directly under the halides. I recently changed my light bulbs in my sunpod 150 watt X 2 for the first time to 14K Phoenix bulbs. This week they are running at 7 hours. I cant think of what it is either. I dipped them in an iodine dip just to be sure. Can it be a fungus of some sort? I am having a polyp of purple hornets comming on wednesday and im freaking out cuz i dont know if it will be safe.... This is one of the first corals i got and its been in my tank awhile. When i got my light fixture the bulbs in it were already 9 months old so basically none of my corals have seen new bulbs unitl now. Everything else is fine and i started out at 4 hours of light the first week i got them then gradually went up an hour each week. Please help

Unless you see something on them that looks kind of like pimples I don't think it would be pox. Do you have any pest anemones close to them by any chance, aiptasia or majano? What about any nudibranchs or asterina stars on them? Did anything fall off of them during the iodine dip?
Hopefully it is just their way of adjusting to the new bulbs and they will pop out again soon.

That is an interesting idea. What is the peroxide supposed to do to, or for, them? Would this be akin to boiling infection out of a cut on our skin?

I just read a post on another site where someone bought the latest and greatest skimmer. In the few months he ran it, the water quality dropped and many of his prized zoa began turning brown. He put his old skimmer back on with a better pump and in the past couple a weeks the colors are returning as parameters improve. I'm not sure this is the "only" thing going on in the system, but it may warrant some thought???

Good point Hop. I remember someone once told me that zoanthids would be happy growing in a mud puddle.

Dont know. But the people of Reef2Reef are all about hydrogen peroxide. Its suppose to kill off any fungus afetr bubbling for about 5min. I did it last night and it seemed to get rid of some of the brown and more of the zoas are opened today

Please keep us posted with how that treatment goes as I am very interested in it.
Did you dip the entire colony in peroxide, or just use something like a Q-Tip to apply it to one polyp at a time?

I filled up a small bowl with tank water (enough to fully submerge the colony).. Then put in your regular ol run of the mill hydrogen peroxide cap by cap until you see the zoas start to bubble... Then let them sit for about 5 min. After that while they are in the bowl i used a turkey baster to shoot water at the zoas so that it can get between the polyps. The i rinsed the colony off with tank water before putting it back into the display. The ones that were really brown didnt recover but the others even ones that had a little brown recovered and by today were fully open. I also moved the colony to the sand bed so that might have helped also.

Thanks for following up with that information. That is definitely something I would have never thought of trying, but it appears that it was not harmful to the zoas in any way.
How are the ones that were the most brown now?
