Is this aptasia?

Thanks in advance

What part of the rock are we supposed to look at?
When it doubt kill it, is a good axiom to remember in a reef tank.

Looks like pulsing Xenia to me, unless there is an Aiptasia hidden in there! Lol

And pulsing Xenia spreads just as much!

Would guess yes, but need a better pic.
Does it retract when touched?

Let it take over the whole rock! It's beautiful.

I primarily see Xenia in the images.

 

[Stevenlburton]

Thanks everybody

Make that rock it’s own island, the Xenia will cover it and not be able to spread.

^This! I had it on it's own rock because I heard all the warnings, but a little too close to the rear glass that it was able to spread to that. Took over about half of the rear glass before I took it out. This stuff grows like a weed. Not Aptasia, but if left unchecked it can take over a tank quickly.
