zoanthid eating imposter

Hey Karin,

There is a really helpful presentation in the Reference section of the Library. You should check it out here:

Main thing is that you should not assume that you got them all, because if you found one or two, there could be eggs you've missed and then lots of new ones next week!

Good luck with these guys. Not fun.

The egg cases are spiral shaped and won't be killed by freshwater or iodine dips. You have to pick them off with tweezers.

Those zoas will do fine in an unbuffered fw dip. I take a cup of RO water and add a little Seachem Reef Dip and vigorously shake the zoa frag or rock around to dislodge any and all pests and critters. Let it sit for a minute or two and shake again. You can also use Lugol's (one drop will do in a gallon) or Revive coral cleaner. I have good results with all. Before placing it back in tank, dip in tank water or fresh untreated RO.

Here's what I have done in the past... do this at your own risk.

I take the rock/coral out

run it under cool freshwater in the kitchen sink, making sure to carefully inspect the polyps for any eggs before putting the colony back in the tank. I haven't had any coral losses yet.

the first couple of times I would cover the drain hole and have fun killing the nudibranches afterwards. My tank has been nudibranch free for months.
