what is this? xenia? mojano?

[THE WOOKIE]

have had this peice of rock for about 3 weeks. it came from something fishy in RI (very well maintained place) so i doubt it is mojano or aiptasia. it was pulsing earlier like a xenia would. got me a little worried because it is taking over that corner of rock and spreading fast.

forgot to add that it has tripled in size in the past three weeks

 

[THE WOOKIE]

just googled that looks very similar

Anthalia?

looks like pulsing xenia to me, they like iodine if you want them to flourish squirt them with some fresh water if you don't, it burns them like salt on a snail. mine seem to pulse more when alk is high, it will climb up onto anything you place above it

Green star polyps usually grow from a purple mat. As the purple mat expands, the GSP cover more ground.
Do you see a purple mat there?

I think there's another kind of polyps, (woods polyps maybe?) that don't have a very obvious purple mat. People find these to be a pest.

 

[THE WOOKIE]

nope no purple mat

Looks like anthelia to me.

I agree that it seems related to the "dreaded" purple mat cloves...................

 

[THE WOOKIE]

so get rid of it or leave it?

Cant tell from the pic but, does it have white centers? If it does, i say definitley star polyps. Just like GSP, only pinkish in color, if you leave them they will start creating that purple mat that Moe_K asked about. I would leave it if you like GSP.

 

[THE WOOKIE]

yes it has a white dot in the center. going to leave for now and see what it does

At first I thought GSP, then maybe hydroids and now I am thinking xenia. Following along to see what they turn out to be.
Closer pic would def help ID these!

 

[frank180reef]

well if it is xenia it would pulse
to be safe move the rock away from other rocks

Looks like anthelia to me.

It's GSP you can see the purple matt and the generic GSP polyps, they're browned out but still there
