I haven't had this problem before, but 99.9999% sure these are zoa eating nudibranchs. Looks like I'll be picking up some coral Rx unless someone with experience knows of something better that's completely reef safe. Not interested in getting a wrasse or other pest eating fish though. These are in a 20 long that is going to be used as a quarantine tank when my main tank is set up next week. I have hammers, Duncan, favia, goniopora, montipora, cloves, xenia, green star polyps, ricordea, lots of zoas, reef hermits, snails, diamond goby and two clowns. There's about 12 lbs of live rock in the tank too. The xenia and live rock will be staying in the quarantine tank, everything else will be moved to the new setup after I'm sure it's pest free.
