If they are the true protopaly's or grandiose ones that carry the palytoxin I'd just make sure to have gloves on and run carbon, unless it's a small tank. Carbon would absorb most with enough volume. Most of the ones that carry the toxin are large and green or brown, you can see the striations in the body. They also do not grow in a mat, they grow on stalks. Yours do appear to be actual paly's in this case, not the Zoanthid Giantus (or however it's spelled) that a lot of times are sold as "Paly's."
Years ago I went down the palytoxin rabbit hole as I was reading a bunch of horror story's. Turns out it's not as deadly as you think, unless you really get yourself directly in an open wound. Even then, if you start tasting metal just get to the ER and get the antivenom, it's not instant by any means. You have time to react.
Other way would be bake the rock and inhale the toxin, for the love of god NEVER cook a rock with a zoa/paly. The likelihood of palytoxin in Zoa's is low, not as low with paly's, but the damage an airborne palytoxin wreaks appears to be devastating.
I'm all about natural methods, Wrasse, Dottyback, let them feast lol Safer for all
PS: Been years since I've dug into too far, anyone feel free to correct me if I'm mistaken. According to my wife, I do tend to be wrong.....occasionally.
