Red Monti cap bleaching or something need advice

[Dre]

I Can't up load pics at the moment. My Red Monti cap is bleaching or being devoured rapidly. Yesterday I noticed a white blotch the size of your pinky nail near the edge of the colony. Iv'e seen this happen before but the cap recovered. This time whatever is going on is spreading fast. Pics not uploading I'll continue to trying. Until then your help is always appreciated.

you sure it's damage? Red monti is white on the ends where it's growing

 

[reefiness]

are you actually noticing continuing recession of tissue, or was it just a one time loss of tissue. Ive had that sort of thing happen to me when another coral stings the cap. loses tissue quick then regains it rather quick as well, usually within a week or 2 depending on damage amount.

continuing recession of tissue

Not sure what's the cause. Tissue is still receding and still can't upload pics

check the bottom for nudis

None of those. I saw a large bristle worm on it last night. I tried to grab it, i only got it's head. I don't know if that's the culprit but the cap still receding fast.

Montipora eating nudibranch. I just spot one underneath the colony. Damn

Summer is winding up, but the biggest problem I have with SPS if all other things are equal, is high heat. 84F+ for a few weeks. Next in line is high phosphates over a longer period of time, >0.02 ppm, but them together and SPS die off. Hits me every year.

Biological predation is hard to ID, Is the skeleton bare, tissue consumed? or bleached? Hopefully you've got the right culprit. I'm not up to date on how to handle those, are they the same as AEF or zoo eating nudi? so many pests now and days, I wonder if EXIT will work on them.

do you make , any change ? like add more , or , replace the GFO ?

The red tissue is continuing to dissolve outward leaving the white skeleton. No critters visible where this is happening but caught two tiny white nudibranch underneath the cap. I Saw a youtube video confirming they are Montipora Nudibranch. They claim these nudibranch are very difficult to get rid of. They have a high tolerance to treatment and the eggs are not affected this. They Probably came from new corals introduced several weeks ago. It will have to run it's course, not treating the tank.

Something similar happen to my cap , couldn't figure what was the couse , didn't spot any pest - I started to cut of the dead part and it stopped spreading - just my experience.

If you play it out they will lay more eggs and if you have other Monti they will find them. If you found two they are many more. You can remove cap and qt it. Cut off the dead pieces. Dip and dip until the eggs hatch. Six line wrasse and others wrasses can keep them at bay by eating them. At night when the lights are off. Shut off the wave makers or strong current. Get a flashlight and look on the monti. You might see a lot more. Or your in the beginning stage. People should start qt coral even if you dip. The eggs will survive.

I place there live nudibranch in the dip solution for 25 mins and it killed them. I'm Gonna dip the rock and and dip it again next week. I have a small yellow wrasse as well. Hope it work out for the best.

Dre, I got red monti if you need to refresh when all is done.. sucks.

 

[piranhapat]

I read that they eggs hatch in 14 days. So doing it every week for a few times will be good ideal.

Like homegrown stated check phosphates as a culprit. My birdsnest withered away with high phosphate.

Just got done and the receding have stopped. Will do just that.

This isn't po4 friend. After close observation i saw the tiny nudibranch. There bite seem to cause the coral tissue to melt away.

Here is a good read. POTASSIUM PERMANGANATE can kill eggs. How much and where you get is another story.
