Found these guys today in my refuge, I just want to know if they are gonna do any damage to my system, I have SPS, zoas, and a couple of LPS in my tank. There are some zoas in my refuge and I didn't see any of the nudis on them but it has only been a couple of hours, and have yet to do a night check. I did have one colony of zoas close up recently and put them in a nano to see if they would recover, they have been opening slowly and I have yet to see nudis in that tank. If these are a threat, which is the best way to get rid of them... http://reefcentral.com/gallery/data/500/109020IMG_0989.JPG

Don't kill them, don't kill them. Remove them and then sell them on EBAY as rare sea slugs.

Start preparing the zoo dip....

Putting your zoos in a QT tank for a couple weeks while the ones that aren't on your zoo rocks die off from starvation.

These things are an INSANELY annoying pest.

Edit: those three curly looking things on your first picture are egg sacs. If you've got them on your GLASS they're probably ALL OVER your zoos.

Yeah I knew the eggs where there, didn't notice them till after I cropped the photo though, I am preparing to do a dip and manually remove for now, I don't have a qt tank yet, but we'll be getting one ASAP. Thanks.
