Agreed they are plays. I had an invasion of those too in my old tank. I eventually pulled out the rock because they are hard to get off and continually grew back. Never tried the kalk paste so that's good info. I used to try to pull them off during a water change which helped. Never really had any symptoms of palytoxin poisoning myself.Those actually look like palys to me, not zoas, although I'm not positive. Regardless, you should always play it safe when messing with zoas.
I've been steadily removing some trash palys from my rockwork in the tank during water changes. These are the highly toxic kind that are known to contain a lot of palytoxin so I play it pretty safe.
What I do is wear arm-length gloves and use a small tube (I think it's 3/8") to create a slow siphon for a water change. You want a small tube to create a slow siphon so you're sucking only a small amount of water to give you time to remove them. I then proceed to pull the palys from the rockwork with tweezers and suck up the removed polyps and any slime/palytoxin that gets released in the process. That way it doesn't disperse into the tank and cause problems for the other tank inhabitants. I try not to remove too many at one time and then run some fresh carbon after the water change just in case some palytoxin got released. I've had pretty good success with this so far with no issues to myself or my tank. I would also recommend keeping any kids/pets/etc away while doing this just in case.
Or as @James M mentioned you can use kalk paste or F-Aiptasia to nuke them in the tank. Just make sure not to get that on any corals you want to keep as it will likely kill them as well.
Yes. I believe they are Pandora’s. I’ve heard they can quickly overtake an area.Those look like Pandoras. Do they glow orange gold in blue light?

I pulled a good amount of them off during my water change over the weekend, but some I just crushed trying to get them off the rock. I have some Ap-x so I'll try that for some of the remaining. Thanks.Red Sea Aiptasia-x will kill them off, same for GSP
I tried Aiptasia-x and they retracted for a few days/a week and I thought they might be dying off, but nope. They're all back fully open and going stronger than ever and continue to spread.Red Sea Aiptasia-x will kill them off, same for GSP
I wish I had done that. Now it's too late and need to eradicate. I've tried pulling them off but that hasn't worked too well.I have pandoras and keep them isolated on a rock. Once they start growing off I trim and toss.
They can be pretty. Just need to contain them because they will grow quickly and take over an area before you know it.And I just got me some pandoras...
