How to dispose of palythoa?/soft corals

[Silverfish]

Not trying to high jack but seems this is relatable. I have a zoa garden with purple monster palys. They seem to want to spread every where and take over. How do I remove them from the others? They are all interspersed.
thanks

Sounds like an excuse to make a run to the ocean and free them.

Perfect way to put a species in a part of the ocean that doesnt belong
