Are this montipora eating nudibranch marks?

Hello all.

Well I'm starting to see signs of a pest in my corals. Could this be marks of NEM?

What could be a useful in tank treatment?

Thanks for the help.

Have you seen them? I found them on my corals super early in the morning before any lights came on. They were all lined up along the edge. I hope it's not, because they are not fun to battle. I lost most of my montis while trying to isolate, qt, and treat.

Yes I have see them. But those marks are not like the ones of the nudi. I say this because usually they go from a edge eating it... So you see a big white patch that usually starts to increase in size.

This is nothing like that...

What are your parameters? That is going to be the first things the bigger brains want to know when they get off work and start answering questions. Might as well pre-empt it. :)

Do you have an urchin or limpet or something in your tank?

The shape of the marks looks like maybe a more common thing.

Thanks for the answers. My parameters are in this Pic. Thank God for apex and trident

I don't have an urchin. At least not in the main tank. I have 2 in the sump...

No limpet or anything like it
