If it is a manjano they are considered very bad pests as they spread very quickly in the tank. I do not know if they move around, however you may have more than one of them which would explain in multiple places in your tank.

I would keep a close eye on it especially if you do not have any bubble tip anemones in your tank so therefore no reason to have a small one.

It is definitely not an Aiptasia

I have 4 of them. And they definitely move. I’ve only ever had 4 in different areas of the tank (about a year). I initially thought they were bubble tips too but as the one got bigger it just didn’t look the same as on the web. Maybe I’ll just wait and see what happens. I’m still new to this hobby...
