Just found a Nudi - Help with ID!

[T-J]

I know nothing about Nudi's other than some are good and some bad. My kid just found this one in the tank. Help ID!
I used a filter on my phone to help with the coloring. It looks to be totally white.
Thanks!

More importantly than the ID...is it something to worry about? Should I just take it out?

Possible it’s a monti eating nudi. I’d pull it out.

Looks like a monti eating nudi, bad guy

I would thoroughly inspect all monti in the tank, look on the underside. If there is one there is most likely more

Looks kind of like a monti eating nudibranch. Difficult to tell from the picture.

Thanks everyone. Guess that's why I found it by the Monti Cap. Got it out. Will check under the cap for more.

Update: Don't see any others in the tank. I was going to frag and glue the Monti Cap today...good thing I didn't! I was able to lift it out and inspect the underside. The edges of it all look good as well.
I do have a forest fire Digi frag that I just picked up last weekend in there too. A Nudi on it would be pretty obvious. It looked clean too.
Thanks R2R for the fast response! Love you guys!

If it came in on a monti it may have eggs. I had a 3" dia spongeode in my 120 that came out of my nano. Was in the 120 for 3 months no issues then started to die. Took it out and found quite a few around the rim. Fragged it but only one small piece ended up with no nudis on it and disposed of the rest.
Here is what to look for if any montis start to turn white.

I would hold off on glueing it for awhile and keep inspecting it to make sure there aren’t any eggs. You could put it in a bowl and blow it off with a turkey baster to try and dislodge any remaining nudis, they are pretty good at hiding.

Would a Bayer dip kill them off?

 

[Barrett]

It will kill the adults but not the eggs, best way to remove any eggs is to manually scrape them off.
