It's starting to sound like a plague of sorts, Jim. Can you isolate the rocks that have it? May have to take action... :confused:

How fast did you say it was spreading?

Can't seem to stop it Alan..... I may have to call "reefbusters" :rolleyes:

The trouble is it seems to break off and reattach itself elswhere in the tank.

Anybody want some, they can have it. It looks nice but needs alot of harvesting.

Hello Jim,
It's definitely not an algae, nor is it a gorgonian.
The picture is blurry, but it appears to be a small colonial polyp.
Probably in the Xenia or Clavularia family (maybe also a type of Hydroid). I've had it before. It doesn't appear to be very aggressive toward other corals but it does grow quickly.
It would be good for covering rock between larger corals. It would also be good for nano tanks or in a aquarium with decorator crabs.

oh yeah I'm back......

My Martha Stewart will be so happy :mrgreen:

It's hard to tell from the picture,but,it looks like a type of hydroid.

I just nuked a bunch of it about 5 minutes ago. It was growing on the base of an SPS colony and was killing it off. :evil: But, not anymore. :biggrin:

Yeah I got this stuff to and it grows quite rapidly to.

dyereefer......

that is the same stuff I have....

Jim

I posted back in June, trying to identify the growth I am having over my live rock.

Since then, it has continued to spread over my entire tank and has attached itself to the sandbed and even the powerheads and overflow.

I now think it is a hydroid. a link is listed below.

I posted a pic in the gallery (not sure how to post it on this thread) and you can see how it has attached itself everywhere. The problem is, it spreads by the stems breaking loose and floating around and reattaching. If I try to pull it off it makes things even worse as all the stems break loose. It is now on almost every rock in the tank

Is there any type of invert or fish that eats this stuff?

I really don't want to take my tank apart and have to scrub each rock. Being that it is in my sandbed as well, I would have to replace the sand.

any ideas?

:cry:
