Hello everybody,

I have been watching these guys for the past month and they didn't grow or multiplied.
I thought at first it was Aptasia but i had those before and this looks different.

I shot the pictures with the yellow Orphek lens and macro lens, the patches are about
1 square inch.

Thank you

Colonial hydroids?

I've scraped these off multiple times and they keep growing back so...if you can't beat them, feed them! Lol. Are they colonial hydroids? Sorry for the lousy cell phone picture.

I just read the thread and somebody also mentioned parazoanthus.
So I turned of my lights and took a picture with a strong led flashlight and
only the macro lens, I think that maybe it. Let me know what you think.
Thanks

Wikipedia got this from and looks identical to what you got indeed.

Not sure if they deemed a pest by most reefers or not but look kind of cool imo but not everything that looks good is good ha ha .

What you think @vetteguy53081
Can these be invasive ,if so how much so,to give op some more insight from someone who may of had personal experience with them ^_^

These are yellow star polyps and a favorite of mine. These polyps send messages to each other and feed on zooplankton in the water. The Yellow Polyps, often referred to as Parazoanthus gracilis, are an unusually beautiful colonial anemone. They have long thin tentacles attached to a fluted body and single celled polyps forming a group.
Its hit and miss- some evasive while others stick to a rock

Agreed. Yellow star polyps. Most usually say invasive but there are others who keep them with no issue

Thank you,
I think they look beautiful and would hate to remove them. I will keep an eye on them,
I have 3 little patches of them spread about a foot appart but all about the same level.

I will be moving half on my life rock to a new tank in the next couple month, that gives me time
so observe if they get out of hand or if they stay.
