Possible aeolid nudibranchs
 

I have what appears to be two or three very small aeolid nudibranches (trying to get a good picture) on my zoa colony. How do I get rid of them?

There are also several brittle stars living in the colony that I would want to keep if possible.

Any suggestions?

Picked off three throughout the course of the day and don't see anymore... but where there is 3 I am sure there is 4 and a whole lot more. Any suggestions are appreciated.

I do not know the answer to this one. Perhaps OF2F or Wake can help.

Can you post a pic?

Too small to get a decent picture and when I pull them out they kind of are not identifiable due to them being squashed.

I will find a decent picture online or try to take one tonight if I see another.

UPDATE:

Picked off a couple of more (about 6 total) and half of my zoas are now open again. I may try to continue manual removal.

Pictures coming. We got a decent picture tonight.

Can anybody help to positively ID these guys? Should I stop trying to do manual removals and just do a drip? Or are these one of the reef safe varieties of nudis (doubtful)?

Those look like aeolid nudis. I would say that if the zoas are opening up after some manual removal, then they are detrimental to corals. There are a few species of wrasses that are said to eat nudis, like 6-lines, 12-lines, Coris wrasses and Mystery Wrasses to name a few...some of these tend to be aggressive in smaller tanks. Yours is a 46 bow if I'm not mistaken? This might be too small for a 6-line, but a Mystery would be a nice addition. They are expensive; I have seem them for upwards of $200. If you don't have the room for another fish, then manual or siphoning may be the only way to remove them.

Edit: I don't believe that there is a reef-safe Coris Wrasse. I would strike him from the list.
