How to Kill Zoa Invasion

[Toby Flenderson]

I've let these green/brown zoas get out of hand in my tank and the have taken over. They have covered some rocks and are threatening other corals. Some of the rocks i have removed and scrubbed but other large ones i wont be able to remove with out dismantling the tank. Im also wondering if the slime cloud that is produced by scrubbing is harmful to the tank. Here is an older picture of the tank but you can see the issue.

I have the same thing and ive used "aiptasia x" on them. It pretty much kills them it just takes a little longer than it does on aiptasia.

i should have thought of that, thats a great idea. I ''ll see what happens

Well I just spent a couple hours with tweezers pulling zoas and gsp off the rocks I went over the bare patches with a tooth brush afterwards. We will see what happens, I definatly made a dent. Here's some pics, I went through a couple of those Tupperware bowls full. It was a full on zoanthid massacre today.

Don't forget to wash your hands fiercely. Those things can really mess you up.

Thanks for the tip. I'm actually a little freaked out now. I washed my hands but not with a brush or anything. I was in there plucking these things for quite a while.

I have those same palys, and they're like weeds now. There was a little bunch on my old, old overflow that I wanted to keep, so I scrapped them off and threw them in the tank. They just kept growing and growing.
