Montipora Eating Nudibranch Eggs?

[Twosixpax]

Apologies if this is obvious elsewhere - I searched the previous thread but couldn't find a photograph clear enough to ID if these are MEN eggs on the back of a new Monti Cap. I just bought.

The Monti looks healthy enough and the only hitchhiker I found after 2 dips was the one shown (which is darker than I'd expect for a MEN).

Thanks.

First pic are amphipods, beneficial crustaceans similar to pods (though generally larger) and can be found in basically every tank. Second pic are spirorbid worms, harmless filter feeders, very common although spread rapidly. Is the 2nd photo just a close up of what you're concerned of in the 3rd photo?

Also this post fits under the "hitchhiker and critter ID" section, just for next time

Thanks for the quick response - really appreciate it.

I thought it was some kind of pod, but wanted to be sure - thx. The 2 photos are of the same thing, yes.

The worms I guess I live with rather than scrubbing off (if they're likely to be in my display anyway)?

Yeah, pretty hard to keep spirorbids out of a tank, they're completely harmless/beneficial however they do spread fast, won't harm anything ofc and are 10x easier to scrape off of glass than coraline.

I completly disagree.
Spionid worms are not harmless.
There may be different species around but mine(and most) bore into hard coral and rock. As the population grows it can really irritate the coral. So much so that that pe suffers and may stop the growth of the coral.
I'm not saying you have these worms from your pic but look like it.

Yes, however these are not spinoid worms, these are spirorbid worms, which are harmless

They clog filters ,clog pumps and intakes and even overtake sump areas
I scrape tem into a net and discard.

So many names that look similar in spelling. LOL

Just for reference: this is a picture I took 1,5 years ago of when I had a mild MEN problem. Removed the Monti cap and haven't seen them since fortunately
