What is this weird plant like thing growing on my rock.

 

[cmcoker]

I'm assuming the upper rock. That looks like caulerpa

 

[KJ]

Caulerpa taxifolia.

 

[Aidanwolf]

Yes the upper rock.

Weird it just popped up out of nowhere and I have had this live rock for a few years now.

 

[Aidanwolf]

What should I do about it.

looks like it's bryopisis I'd cut it suck it out and then put some epoxy over it or u could get a tang and maybe he would eat it

I think the one bellow the top one is bryopisis and the top one is caulerpa It is weird that the culerpa just popped out of nowhere.never has it been introduced into the aquarium. Also I have a 29 gallon biocube so I would get the tang police called on me if I got a tang lol.
