Rainbow Monti Help

[racermike27]

Hey Guys I need a little help. My rainbow Monti frag has been doing really well up until now. It alomst ncrusted over the entire plug in a few weeks. I have seen great growth. But this week I noticed that my green polyps began turning yellow. So I really didn't take it as anything bad. But yesterday I noticed that there was a piece of the skeleton exposed in the yellowed polyp area. I checked all my parameters and all are in check. I looked around and I do not see any parasites either. I was wondering if you guys could offer any advice.

Here is the frag healthy just last week.

Here are two photos as of today

Notice the white area at the top of the frag. It seems as though the "skin" just peeled away. Also the polyp are not fully extending is there anything I can do?
Any help is greatly appreciated.

Thanks,

Mike

Are there some sort of flatworm or red bugs that maybe you didnt see ? i know they can be TINY!

I looked all over and I really didn't see anything. It is also the only coral in the tank that seems to be showing these symptoms.

I would try giving a small dipping and shaking with a diluted lugol's, it will get rid of any parasites and if anything it will help with any infections

Will definitely try that. I have been looking and I have not found any parasites. So I will try the iodine dip.

Roger, what ratio should racermike27 dilute the lugol's?

Looks to me like it may be a lighting or water parameter issue. What are your Ca, Alk, Salinity, Nitrate and Phosphate levels at?

I would probably try 5 drops on a 1 qt. container
