aptasia id

As the thread title says, I’m 90% sure this is aptasia growing on my monti frag plug. I did not notice it early because the frag and plug were sitting on another section of the tank and the light was too high so it started bleaching. I moved the plug this afternoon and noticed this guy...

Hello, I’m new to reefing and need some help. I got this daisy zoa and it came with this things growing with it. I’m hoping its not aptasia because I have used aptasia F and kinda killed alot of my clove polyps. What should I do?

Looks like aptasia but has crusty calcified looking tube base comes in out out of

Hey y'all, just grabbed this guy a few days ago, and today when lights were on full blast I saw this little guy at the bottom of the frag plug. Is this aptasia? Or something harmless? It does not go back into it's tube when touched. Thanks tons :D
