Can anyone idenify this stuff, its taking over

[Chris Hopkins]

Hello
I am fairly new and been in the hobby about 2 years, been going ok until this stuff showed up, the one pic is after 3 days of no light, the other is after about 30 minutes of the lights coming back on. it is on my rocks and the overflow as you can see, my parameters are all in the normal for what I have been told by my LFS, the only one that is high is my nitrates which are around 30, I am dosing BRS 2part. any help would be greatly appreciated.

tank 250 gal

mg 1350 tested with salifert
calcium 421 tested with hanna
alk 10.2 tested with hanna
No3 30-50 tested with salifert
Po4 .o3 tested with salifert
amon and nitrite 0 tested with salifert

thank you

are you referring to the polyps themselves or the web like stuff inbetween them?

 

[Palyzoa]

Looks like a type of clove polyp which can be very invasive.

 

[MDeVito]

They look like developing star polyps

Should be "matted" and able to scrap it off with a razor.

@saltyfilmfolks take a look here. Possible hydroids or aiptasia?

 

[reeferfoxx]

Well looking closer it does look more like some type of clove polyp. Hmmm

 

[Palyzoa]

They could as well be hydroids, like mentioned above.

 

[Chris Hopkins]

thanks for the response. going to look into the hydroids and polyp, would be easy to scrape off my overflow but the ones on my rocks will be tough to say the least..

[saltyfilmfolks]

Hard to tell. But yea , should scrape off in a Mat.

 

[Chris Hopkins]

thanks again, I will try to get a closer pic when I get off work.

The repeating pattern of "smooth" 8 tentacles suggest green star polyps

Wouldn't gsp be more of a mat rather than sending off runners like clove polyps?

Great question.

fascinating

ive not seen that as an invader

octocorallia for sure, a soft coral, see the x8 fronds on all of them


anthelia or as stated clav variant with tube stolon mat that's sick man. I can't say that everyone would want that killed, some would culture it and call it mars polyps. pico reefers would love it, that just got out of hand. surgicial precision removal is indicated and its preferable to dinos that's for darn sure.

 

[Chris Hopkins]

here is a closer pic of some of the stuff that is on a rock.

 

[brandon429]

I would now vote solidly for anthelia yep and its in a few threads online as a pest. still better than dinos! good practice starter corals for smaller tanks where its easier to take them apart and clean out the growths as needed. in nature I bet a butterfly fish or something comes along and zips them a bit like spaghetti

 

[reef lover]

Upon closer look I think its anthelia

 

[reef lover]

Lol beat me to it .
