Hitchhiking Nudi's

I recently added a couple of corals to my 10 gallon. One of them being a really nice Frogspawn frag, it's HUGE, and the other about a 2 lb chunk of live rock with button polyps on it. Got both for $5 apiece.
I noticed after adding the rock with the polyps a ton of little worms wiggling this way and that, picking up pieces of sand and sticking them to the rock in what appear to be cylindrical shapes, so I imagine they are feather dusters. Correct me if I'm wrong. Please!
Then I saw what appeared to be a micro-sized Snowflake Eel, which was in actuality a Peanut Worm after researching. Hey it was white with black bands... Then I saw a bristle worm under the back edge of the rock. Lots of cool stuff coming out of this rock I got.
Also, I noticed some kind of little spikey brown thing crawling around on the closed polyps but couldn't get the camera to zoom in enough to really tell what I was looking at. Later last night I saw it on the glass, and reallized it was a nudibranch of some sort.
It is brown, with thorny looking protrusions from its body, with two antenna's and a clear, tear shaped tail, much like the one on the Hitchhiker ID thead. It is only like 1 cm long so it's hard to see all the details. I also spotted a second one before I went to bed. Anyway, I imagine I should have removed them but I was happy to see more oceanlife coming about in my tank at the same time. Anyone have a clue what kind of nudibranch it is and if it is going to be a pest?
The corals possibly at risk in my tank are Green Star Polyps, Button Polyps, Frogspawn, and Purple Ricordia. Are these a nudibranch buffet?
Thanks in advance.

Well, I thik the fact that you found one ON the corals, is enough reason to worry. Although, where there are 2, there are likely 3, and where there are 3, there are likely 4, so on and so forth...

They sound like the zoo/polyp eating nudis, you should probably fish 'em out ASAP. I had a few of those munching my zoo's, clove polyps and button polyps. Good Luck

My main concern honestly was with the other corals I have in my tank.
I'm going to syphon them out when I get home from work just to keep them from reproducing.

I think they really only munch on "polypy" types of corals, so SPS and LPS should be ok, I think there may be a SPS eating nudi, but not 100% sure.
