Green Palys ok ?

[Reef23]

I have two large colonies of these guys on two of my large pieces of live rock. I really like the look of them but I have been reading a lot of horror stories lately about the toxins and such. I don't want to risk these guys doing any damage to my acans or taking over the tank. Any experiences with these ? Worth keeping ? I'm moving tanks in a few weeks so now is the time to get rid of these guys.
