New Xenia coral?

[saltwatercowboy9]

I have growth off of an existing pulsing Xenia coral. Is this new Xenia growth or something else? It’s to the right in the picture and underneath. It’s somewhat see through and structured different.

looks like something else to me, perhaps macroalgae of some sort. xenia still looks like xenia as it spreads (and believe me, it will spread, even after you wish it would stop)

Looks like Aiptasia. If you look below the Xenia you can see one as well.

Ohhhhh noooo I’m new to all of this. What do I do? That’s exactly what it looks like.

+1 the growth to the right does look like Aptasia...hopefully not though!

I just noticed another one in the middle of the tank.

Aptasia X in the oral disc will kill them.
