Zoa spawning

I think my zoas spawned! What do you guys think? My main zoa colony is on a different rock structure than this small one, so it’s really cool to see coral spawning naturally in my tank!

How do we know it didn’t detach or get knocked off and settle elsewhere? Not trying to rain on your parade. Just a question.
I looked it up online when I saw it there, and I read that zoas can spawn, so I assumed that’s what happened. When I first noticed it, it was tiny. you mentioned it could’ve just detached or been knocked off and settled elsewhere, which is a fair point. I thought about that too, but in my experience, whenever a zoa polyp gets knocked off, it usually doesn’t survive I’ve never seen one reattach somewhere else. That’s why I’m leaning toward spawning. Part of the reason I’m sharing this is to see what others think—maybe I’m missing something.

Just that zoas showing up elsewhere without spawning (asexual reproduction) is very common and zoas successfully spawning (sexual reproduction) in a reef tank is exceptionally rare. Like everyone’s personal experience vs almost no one’s personal experience.
 
It might be easier to tell once it's grown out some more. If it looks like a completely different phenotype from the others then it could be spawned. But I've seen singular zoanthid polyps appear in new places before
 
That's the best!

Before the Acan fad, I had one pop up on rock from Marine Depot. I was a lot of fun to watch grow into a coral.
"Before the acan fad" & "marine depot" was probably before a good 30% of our active members were born Gresh! Haha

I gotta say, its good to still have some of the OGs in these threads
