i have a melarnus and a yellow coris wrasse in my 75g and they weren't able to keep the nudis in check. The nudis are mostly nocturnal so the wrasses don't really get the option to pick them off. Honestly I would just toss the frag out. I did what you did, sucked/scraped the nudi off, and then did a dip. while in the dip i used soft brush and cleaned the frag. A month later they were on the underside of every monti in my tank.
