Need an ID(picture included)

[joshinjosh]

i just noticed a ton of this black/white stringy algea looking thing on all over my rock. anyone know what it is?

 

[NaH2O]

As it grows, does it change from the spikey look? In the second picture I can see a piece that has a fan looking blade (white in color). I wondered if the spikes start to fan out?

 

[reefnetworth]

appears to be filter feeders. do they open? or stay as they are? REEF-ON!

 

[james734]

Is it algea or little feather duster worms? Looks more like little Feather Dusters to me.

 

[returnofsid]

I'd say it's a small feather duster colony. Filter feeders.

That is a social feather duster colony. They are what we often call "Cluster Dusters" At times these guys get so thick they often take over the whole tank it seems. Some of these have runners almost like plants ( not those in the pic). Some of these dusters are very very small ( <1mm dia tubes) and some are rather large ( few mm dia tube).

Nice ID Returno

Clusters with parchment tubes . Each duster is by itself not attached to any other duster. Just like those in this post.

Clusters that are attached to each other with runners and produce a calcareous tube.

I had some nice featherduster clusters in my 29 until the hyposalinity. At first, they seemed to be multiplying but by the time I got down to 1.009, they were all dead. Bummer, I was hoping they'd survive the ordeal.

 

[joshinjosh]

uh i dont htink they are feather dusters at all.... they don't even retract there just sitting there..

 

[BJTenn]

I don't know much, but they don't look like ANY feather duster I've ever seen!

 

[joshinjosh]

i agree, they dont even have radial symmetry

I don't know much, but they don't look like ANY feather duster I've ever seen!

 

[Boomer]

I'll have to agree also Josh. I think some of us jumped the gun. It appears to be a bad week for me doing that Need to slow down

There are some algae like that. I'll talke a look later. Be nice to get a clearer pic.

 

[steve-s]

Better pictures would definately help. I would almost lean towards a Bryozoan. Alot of similarities to Caberea sp & Bugula sp.

Cheers
Steve

I see aptasia there & a porcupine but what do I know

 

[returnofsid]

LOL Porcupine was my first thought...but then I wondered to myself....Hmmm, there's a porcupine swimming in this saltwater tank. Wonder how it managed to open the front door to the house!!!???

 

[Boomer]

Need a better pic Josh. I can't do much with that. I can't think of nothing that grows like that, other than that fan in the middle looks like a very small Udotea sp algae. What ever it is is very odd and has my attention

 

[toolman]

It is an algae, some type of Udotea sp. Lots of small green fans that begin a reproductive stage (your pic), disappear, and then return in even higher numbers. No control except physical removal.

 

[BJTenn]

I don't think you are any closer than yesterday Joshinjosh! I'm gonna keep up with this one.

Hey Joshinjosh, I think you got everybody stumped! Have you found anything out? At all??
