Natural predator to montipora eating nudibranch

[jdubDaReefGuy]

I’ve discovered a few montipora eating nudibranch in my reef tank. Anyone have any natural cures? Do any fish eat them? I have a 9g nano so it can’t be anything big. If there are no natural cures what are other ways to eliminate them?

An m67 frag will do the trick

Not much room in a 9g for predators. Are the montis still on plugs? If so take them out and use a coral dip like CoralRx

Lined Wrasse (6-line wrasse) will do the trick. Any of these wrasse are agressive. Likely you can use a 6line wrasse and rehome him when the pest is gone.
For small tank like that, I just remove all the Montipora. Frag them and keep them isolate until they starve them replace. These nudibranch don’t live on living tissue but on the LR next to the coral. Just cut the coral off WITHOUT ANY live rock and that piece should be pest free.

A wrasse will eat them.

I have a small A. twistii , about 1.5 inch, and she eliminated all the Nudibranch from my frag tank over time. I only have small frags in open rack. I moved the frag around the rack and every few days, after moving I turn the frag upside down for a day, exposed the plug. I moved them from one side to the other to make sure ant eggs that hatch get exposed to the wrasse. No evidence of any after about 4 weeks. None now for the last several months with out moving the frags.

Would a pink streaked wrasse work the same? I’ve read 6-line tend to be aggressive and I fear with the small tank space it would go on a warpath with my other fish.
