Zoa nudibranch question

[gtp0083]

I thought I had finally rid my system of zoa eating nudibranch. I created a zoa garden so they are all glued down to a piece of live rock. Well the nudibranch are back!

Time to start another coral dipping routine.

Is it okay to dip the coral with the piece of live rock? Or should I remove them from the live rock and wait until I believe they are gone and re glue?

Dip it all..

Okay wasn't sure if the dip would kill all of the good bacteria in the rock. But I guess it's only a small piece.

The thing is that quite frankly its too late to not dip everything..
The nudi could be in the rock now.. and if you don't dip that then you aren't doing anything

If you haven't already you might want to build yourself a siphon similar to the one in the link below and start siphoning out what you can at night and as soon as the lights come on in the morning. Dipping wasn't an option for me and my tank is too small for a wrasse so I had to improvise. It was definitely a little tedious, but they're gone now.

The last one I saw was a week ago now and haven't seen one since. I was planning on dipping assuming if there is a nudibranch there are eggs. Zoas seem happy and are open. If I see any signs I'm going to dip again. If I don't see anything I'll let them be. I have removed about 10 with tweezers (prior to dipping routine) and did a dipping routine for about 3 weeks. Didn't see any for a couple of weeks. Glued all the zoas down then a week later saw another one.

Do you have other rock in the tank as well? They may lay eggs on the other rocks. If you have the ability, I would set up a quarantine tank and keep the zoas in there while you are treating them. Any eggs in the tank will hatch and since the nudibranchs only eat zoas, they will starve themselves out in the main tank. I don't know how long this will take though.

From the research I've e done they don't venture far from the zoanthids and typically lay their eggs within the coral.

Still haven't seen anymore but I'm assuming the worst.
