Montipora (only) bleaching/STN

[Snotdoc]

I had same issue recently and the nudibranches were hard to see at first.

Here's one where's it's obvious. Look around the edges and underneath. The egg clusters look like little white clusters. Revive dip kills them but is a little harsh (several of mine bleached pretty substantially). Good luck. They are a pain.

@Paul B I like the beer bottle there. I had one a lone time ago that had blue tunicates on it.

I probably have 9 or 10 bottles in there.

Found some little dudes on a monti tonight after lights out. At first I thought it was nudis, but I think it's just pods eating dead stuff based on the jumpy movement and not the sluggish movement that I've seen from videos of monti nudis.

That looks like an amphipod too me

I had a similar issue in my SPS only tank and it turned out to be MENs. I had to pull all the Monti's and QT them. Dipping every 3 days. Only half of my monti's have made it so far. Its been almost two weeks and for the ones left they seem to be doing better. Seems like a plague or MENs going around. Have you recently added any new corals/rock to the tank?

what did you dip in.
