What are these white spots?

I have this Montipora capricornis, I've had it for about 10 weeks now. It has started to grow, but today I noticed these white spots on it. I don't think it's bleaching because I only have it under 4 x 54w T5s, although I guess it could be potentially. My other guess is that it is growing new plates or appendages. This is my first experience with this so I wanted to get other's opinions. Thanks. Sorry for the blury picture, but I think it should work.

You could have moni eating nudibranchs.

That could be it, but I've had a monti digitata before for about 4 months with no problem, and I have had this frag for about 10 weeks with no problems, I don't know if they go into hybernation. I haven't added anything for about 2 months. I guess it could, I will look into it.

 

Well, I hope it isn't the Nudis but it could be. Looks like the frag isn't attached to anything so you may want to take it out and look at it under a magnifying glass. I've never had them but I remember seeing the thread above a few weeks ago. I hadn't even herad of them before that.

 

I just looked up some info on the monti eating nudibranches. They can survive without eating for months. So I guess there is a potential that they have been in there the entire time.

I have also just inspected the coral closely and have not seen anything on it or around it. So I guess I will just have to see what happens. Anything other advice or suggestion are greatly appreciated.

 

Here is a thread with some good info. Monti eating Nudis - zeovit.com

Also check on the underside they supposedly hide there during the day. Looks like there are some wrasses that can keep them under control. I found halichoeres iridis (radiant wrasse) mentioned several times. Amsterdam reef (zeovit) - e-Coralia Nice tank pics in that link.

 

I just dipped it in some lugols solution. I didn't see anything come off of it. I used a turkey baster to make sure there was good contact. I used a paper cup and there was nothing that fell of it. So I will just see what happens.

 

Good luck. Keep us posted.

 

Well I think they are monti eating nudis. I looked this morning and the white spots have gotten bigger. So my cap is basically gone. I also had a superman monti that wasn't affected yet, so I examined it, dipped it in lugols and traded it to a buddy to hold on to. (This was actually kind of good because it wasn't coloring up under my lights) So I guess I will just wait a while before adding any new montis.
