Setosa white with polyp extension

Maybe a Six-line but they can be jerks and you might lose fish in the process. Maybe a Springeri Damselfish but they can be jerks also.

Springeri Damselfish and Dottyback both eat some pests. The Damselfish will eat flatworms and there have been some reports of them helping with Nudis so it's a possibility. Melanurus Wrasse and Yellow Coris Wrasse are the two I like for Nudis/Flatworms but they're way too big for a 15 - even for temporary. They also will only help control them, not eradicate them. The Orchid Dottyback may help some as well.

Monti eating nudibranch.

Well it was bound to happen with starting the hobby with no qt. But it looks like I have Montipora eating nudis. Was looking in my tank with lights out this morning and I see a little white thing crawling on my forest fire digitata. This particular digitata has had its polyps retracted for a...

From the pictures, it looks like they're getting eaten to me.

I'd really suggest dipping. I'm currently dealing with acro-eating flatworms and am currently using something called "DipX". The bottle says its also effective on Montipora eating nudibranchs. You could try and find it and test.

Good luck, coral pests are not fun at all.

My options are in the ss. Anything here useful towards nudis?

Honestly I'd consider removing both montis, make sure to remove any visible eggs and Nudis, dip, QT, and then dip again every couple of days.

Here's a great read.

Anything I can add in the mean time

@tbrown3589 I've been gone for 2 days and I came back to fully extended acropora and dying or dead montis. I truly believe it's nudis now. What do you think

 

[GHOSTLY]

Cap has what looks like bite marks as if that area has been ripped away

I'd say most likely it's Nudis. Once all the montis are removed or dead they will start to starve. I've heard it can take 6 months to a year without montis before it's safe to add them again.

Next morning. I can't find any specimens but I notice this each morning

I wanna bump this thread. I did find 1 nudibranch that I dealt with but I've been gone for a bit. All the montis that were being eaten before have magically just recoloured? There's far less exposed skeleton as if it grew back? Is it possible I eradicated the nudis with the addition of springeris and intense dipping?

 

[tbrown]

It's possible. More likely controlled rather than eradicated. It's also possible you caught it early and only had 1. Keep an eye out for eggs hatching!

What signs should I be looking out for? All the montis have grown over their dead skeleton so im hopeful

If they've grown over all that exposed skeleton already that's impressive! Just watch for new damage or signs that the Nudis are back. Hopefully it'll be under control and you're good to go.
