I dipped my shipped corals when they arrived except my finger leather that I bought from my LPS. Now I just found a nudibranch attacking one of zoas and am wondering if he hitchhiked on the leather (of all the corals I didn't dip - why). I just put a six line wrasse in my tank 3 weeks ago for my bristle worm population. Will she take care of nudibranch? What are my other options for eradicating them?
