RTN/STN?

I got this tabletop from Indy in Dec. and it has been doing very well. It lightened up a bit, due to my low mg levels, but it was doing well until I looked at it today. There was a small part of tissue loss in the middle of the base, plus this part. Does this look like RTN? I need to know if I need to frag the top off so that I don't lose it.

Is the tissue just coming off in small pieces or is it slowly receeding. If you have flatworms, you should notice small patches of lighter coral tissue where they have been feeding. If it looks like STN or RTN, I would frag it. I have also heard you can put super glue around the receeding area to stop it, but I have not tested it.
 
Before you frag it, what are you parameters?.. have you calibrated in a while?

Look for spots in the dark area of the coral.. eggs. and eaten areas.. move the coral.. could be a crab or something picking on it. if everything else seems normal do a night check to see if you have acro spiders or any other kind of pest
 
Thanks for the info guys, I really hope it's not Acro eating FWs, now that I just got rid of the RBs. I wonder if killing off all the RBs helped the FWs out a bit. (Probably not, just Monday AM thinking).

The coral looks about the same this AM as it did yesterday. I moved it up to my frag tray for closer observation. I'm heading out of town tonight so I'll check on it when I get home after work and if it looks like it needs fragging, I guess I'll give it a shot.

My parameters are as follows: 400 CA, 10 dKH, 1290 Mg, 1.024, 79-80, pH 8.1ish.

I did have a leak in my ca reactor late last week, (I need to update your skimmer thread Marc), in which I lost 10-12 gallons on the floor, so adding ro/di h2o may have caused a slight fluctuation in salinity/temp but the more I think about it, the more this looks like a predatory (FWs, etc.) rather than RTN.

Well, I've been doing a lot of reading on AEFW today and it appears that I might have them, and some people believe that they are more prevelant after an interceptor treatment due to the stress imposed on the corals.

Here is a long thread about them, along with this one.
 
Well, I'm going to take out that one colony that I "know" has them and really look over it w/ a mag glass. I guess I'll try a strong lugols dip, even though all my acros get one upon receipt. Besides that, I may have to get some of the Tropic Marin Coral Cure and start dipping.
