What do you guys think about doing a fresh water dip to get rid of them? They seem pretty easy to remove via a ...
Can you post a pic of the infected area? Let me see what the area you are looking to dip looks like.
It would be the whole colony. It is on a single rock that I can easily remove without disrupting anything. I am now wondering if I should bother with a dip as I pulled one last nudi out today (only one I saw today) and 80% or so of my zoa colony is open.
You can see a pic of the colony in the pictures section. It is about twice as open now as in the posted picture from yesterday.
I've read that you can kill nudibranches with a shot of high salinity water using a baster in a bucket of tank water or use a wet/dry shop vac and vacuum the liverock/coral, or your back to squashing them with regards to the fw dip The osmotic shock involved in the FW dip will damage and even kill outright much beneficial flora and fauna on and in the LR most are more delicate than the nudibranchs. good luck mate
My zoa colony has been 100% open for several days with no signs of nudis. My guess was there were some adult hitchhikers that didn't drop eggs in this colony. I am glad I went the manual removal route. Thanks for the input all.
