Overnight, one of my zoas attached itself to the shell of one of my hermit crabs! Is this common? my rock anemone also destructed from the rock and attached to my glass. Any tips on how to safely get that back to the rock? Or is it better just to leave it?

It happens. Hard to imagine the crab would sit long enough for that though? Could it be a nem?
It’s possible, but it looks like the zoas I have on the rock. the hermit crabs do sit on that rock more than anywhere else in the tank and some stay so still I think they’ve died at times

How sure are you those brown guys are Zoas? Look like pest anenome to me.
I’m actually not sure at all! Someone suggested in my first thread that I may have pest anemones on the rock stinging my GSP causing them to sometimes stay closed. I replied to them asking which one they were referring to as there is one on the rock I’m sure is an anemone (I’ll add a pic) but they never replied. Later, someone else told me they were zoas and I told them I didn’t think they were due to their bland colors but they assured me that’s what they were. They seem to be growing and are almost always open even if the GSP aren’t.

They look exactly like majano nems. See pic belt for reference. This one is a bit more colorful, burn they come in brown, green, red, and pink

I wouldn’t mind them if they had colors like that! Is it something I should worry about spreading to other parts of the tank or killing my corals? If so, how can I fix the problem?

Um worry, no. Do something about before it spreads hopefully, yes.

They can be and will spread. Not as fast as aiptasia though.

If you can remove rock. Easy to kill them.

In bucket of old tank water, inject each one with a lemon juice and kalk mix. Right in the mouth with a needle.

Wait a few minutes, whoosh rock around in old tank water and then place rock back in tank.

If cannot remove rock, do the same, just a few of them every few hours.
