      Hi Vince, it's those Monti-eating nudibranches--not sure if it's cause or effect but where are the SPS's losing tissue--top or base? Bob

            Manually siphon out at many as you can see/ get too. Dip your coral in Seachems Reef Dip, and then make sure you find and remove any egg casing you find they usually hide under the base of your corals during the day. Don't just check the Monti's they will also hide and lay eggs under other corals.
            Good Luck.

              Thanks Brian...

              I checked about reef dip in PA...and I found that it contains Iodine..

              Can I use other brand if it contains Iodine? I think I can't get reef dip ASAP

              in my country so I should import it..

              I am not sure where it came from...but I think other corals looks OK except

              digita....

              ther speed of their population is so fast?

              I am little worried.

                  There is really no know way to get rid of these with any magic dip.

                  I've had them on and off for over two years. Just when I think they are all gone they come back. The offspring can be so small that a hand lens is needed to find them. It's next to impossible to see them when you remove the coral from the water so I always place the piece in a bowl of tank water for inspection. If you have any plating montis I'd suggest you frag those down to small pieces so there are no folds or cracks for them to hide in. If you only have them on a digi at this point I'd consider removing that colony and it rock base from the tank before they spread to other colonies.

                  I've tried real strong doses of Lugols and it really doesn't do much if anything. Also in my experience montis don't take well to FW dips of any duration long enough to do anything to the nudis.

                  Good luck...

                    The Dip alone does not do it. I did all three things to rid my tank of them. I would commonly find egg clusters under the bases of other corals. Siphon, Siphon, Siphon. The only attack your Monti's, but I have seen them hiding under other corals during the day and feeding more at night.
                    Yes any Iodine will work. I'm with GTR I would not do a FW dip.

                          Vince,

                          I am also dealing with these at the moment, I have been manually removing them for about a month or more, these are the worst of all predators, I am close to removing all of my montis out of the main tank, without any host they will die, I figure worst case I can re-stock the montis in a few months...


                          Best of luck...

                              Vince, PVP iodine or Lugols dips also work (10 – 15 drops per liter) for 15 – 20 minutes.

                              It is recommended for a 2 – 3 week period every other day. The eggs are not affected by the dip. The nudis have a very short reproducing interval so dipping the corals every other day should work fine.

                              I know some people had luck with Haliochoeres chrysus, but others reported the fish does not eat them. It seems to be very individual.

                              Good luck,
