Sorry man. Last sps tank I had with montipora I had in it was devastated by those little evil creatures. I ended up removing all of them. The frag I got that I believe brought it in showed no signs, was dipped 3 times 4 days apart and months later I noticed all the Montis had signs of MEN. I went back to the vendor I got the frag from and all the montis in their display was riddled with them, and the shop owners didn’t even know. It’s something that sneaks up on you unless you are really looking and usually when you do find them it’s very advanced. There are lots of people that live with them and keep them at bay with dips and predators. You might want to give that a try. But I found that removing all Montipora for a year was what worked for me. Good Luck
