Is it common for zoas to move around on a plug

[SBosko]

When I got this plug a few weeks ago they were spread pretty much in a line. Over the last few days it seems like all but one polyp has lifted and they all bunched in and cuddled up close. Is this common? There's not too much flow on them, I just don't wanna come home one day and they're nowhere to be found.

It's very common. The lower the number of polyps the more obvious it is to notice it. Nothing to worry about.

I haven't seen this in person but I don't think they move often.
