Green Montipora getting spots

[chuckfu5]

Hey Guys,

What would / could be causing this?

Alk 8.4
Mag 1400
Cal
450
Nitrates 5 - 6
Phos .02

It's still growing like a weed but I love my green color. Also I've lost all my green color in my grafted monti.

This is very bad
That looks like Montipora eating nudibranch damage to me! I lost all of my montipora's to those evil little jerks.
My advice to you is to set up a quarantine tank and frag all of your montipora's then dip them in Coral Rx and hope for the best.Do not keep the rocks that your montipora's are mounted on.
You should have no montipora's in your tank(display tank)for atleast 1 year.
Best of luck

Thanks for the advice. I just looked up the nudi' s and I don't know. The spots don't seem to be getting any bigger and I have not seen any pests. Those spots have been there for about a month or so without growing.

How fast do these nudi s usually consume a monti?

Had it on my red monti before . Number spot increases over time . after dip it recover . I have a yellow and six line not sure if it help and its on a frag rack .

I agree, looks like nudibranchs. Dip it to be safe, look at the monti and rocks after the lights go out for a few hours.

I stayed up late and got up earlier and say no bugs on the Monti. Also I have 3 others that none of this has affected.

I would dip it to ensure but this thing has attached to all my rockwork and this is in my 13.5 Fluval EVO. I'd have to break it to pieces to get it out.

Do you use two part? I screwed up and mixed them too close together and got some of that calcified precipitate that can occur. Some of it landed on a Hollywood stunner I had as well as a rock flower anemone. Both of them had issues and the Hollywood stunner ended up dying and the anemone had a big sore form which eventually healed. I have no idea why it would cause such a reaction on those two vastly different creatures, but I blame the precipitate for it occurring. Before the Hollywood Stunner died, it first formed white spots where the tissue died similar to how the ones on your monti look.

The only other time I had white spotting that wasn't pest related is when I had an alk swing. Could possibly be chemistry related.

I do use two part and manually dose. I dose .25 ml of calcium in the afternoon to maintain 450.
I dose 1.25ML of ALK after lights off ( 10pm ). Keeps my ALK around 8.4

It looks like the other montis have slight bleaching or slightly pale. I wouldn't rule out nudis just yet. See if a dip helps and pay attention to the other montis for spots.

No my camera phone just takes horrible pics.

I do have a bicolor blenny in the tank....do you think he could be the culprit?

 

[Greg79]

Look at the bottom of it at night with flashlight,
If not nudis presented might be alk swing or some detruits sitting there for a bit

I wouldn't rule it out but catching him in the act might be tough and removing may be tougher.

Looks like nudis to me as well. Good luck. It's been about a year since I got hit by them and I'm hoping that I can go back to keeping Montis again soon.

If you look really close at the margins of the damage, this is where they will be sitting. They hide in plain sight right on top. It will look like a little white fluff of tissue, or even just look like the edge of the damage.

Settling of detritus or 2 part precipitation can cause this but you should have seen something sitting on top of the monti.
The thing that is concerning about the spots you have is that there are spots where settling would not normally occur.

I agree with the others - dip, watch closely, and even throw out the piece if you find them. These little buggers are nothing to mess with - nothing will kill them - ever!
well... starving them by not having any montipora will.

Hope the best of luck to you, and that it is not nudi's.

I got the turkey baster and saw nothing. Stopped the flow and held a magnifying glass above water and couldn't see anything.

When this was a single layer piece and before putting in my Jebao powerhead it would get all kinds of detritus settling in it. Sand, shells all kinds of stuff. It does much better at not collecting now.
It's weird where the longer straight line is it looks like there is not ridges in the skeleton or anything. Like something was laying there for a while and eroded it.
The Nudis don't eat the skeleton do they? Just tissue correct. I'll keep a close eye but I javent seen anything that suggest pests yet.

By the way reef2reef is awesome with all of the help. We have a local club that is great but the participation has dropped off so much.

Thanks guys

I don't think they can eat the skeleton, just attack the tissue.

I also hope we're wrong, and it is just some die off from settling. Those of us who have dealt with MEN's are just ultra careful as Patpare said: we lost everything to them.

Keep us posted as to the health of those spots, I'm curious (and hopeful) to watch the healing process.
