Monti Nudibranches?

[Zachvet]

Hey all,

I’ve been having trouble with a common red monti cap for the past several weeks. It’s developing small spots of tissue damage that appear to be growing in size albeit very slowly.

It is NOT bleached flesh, it is clearly damage to the tissue. Ive noticed what I originally thought was mucus near the damage and coming from the underside of the coral. (My eyes are not great and The coral is about 1.5 feet from the glass so I can’t get a super close look) I’m wondering if these are actually Nudis that are swaying in the flow?

The rock the coral is on is quite large and it will make dipping difficult. I’m considering just trashing the coral if it’s nudis considering this is a cheap/common monti.

None of my other montis (beach bum, rainbow, green playing) seem to have any of this damage yet and I’d like to keep it that way.

Doesn’t look like Monti Eating Nudis, they usually start from the tips inward. Might need more reefers opinion on this.

Mine does this with higher par. Looks identical to yours. It will recover under lower light.

I just had to get rid of a frag that had them hiding in it. I could not figure out why some of the tissue was dying and then I saw them. They only come out after the lights go out and usually hide under and in between the “folds”.

Nightmares. This is why I always quarantine the newbies. I would usually remove the visible adults and try to scrub the eggs away, plop it back into quarantine and observe. Repeat until fully confident they are gone. I notice that montis that have fully encrusted nicely leaving no gaps on the frag base rarely have these nudis.

thankfully this was the only monti in this tank and it never left the frag rack. Sadly, this was yet another purchase from a shop nearby who usually has almost too good to be true prices on their corals, but they always come infested with all sorts of hitchhikers or they die quickly. I usually dip all my corals before adding them to my tanks but I don’t have a qt set up. I just won’t be going there anymore... not worth it.

The problem has definitely developed from the centre outwards, both monti,s have been in my tank for about 4 mths, with no change in light settings. I'll have a look tonight when lights out see if I can see any creatures on them

Thanks all for the input. I’ve noticed it will heal and go through damage in spurts. I got an ICP test and am waiting on the results. I thought about PAR being too high but that doesn’t explain why it will heal itself. I think my water changes may be causing it.

I had them eat from the bottom up through to the top.
Here is a pic on a spongeode.
I pulled it out of my 120 and put it into my frag tank.
I ended up fragging it and have a piece back in my 120 growing.
Have not seen or had any issues in over 8 months.
