ok, what is this?

[tommy in jax]

bought some live rock about 2 months ago. started seeing this stuff on one of the rocks about a week later. now its spreading to other rocks. is it something i need to be worried about? the rock in the picture is about the size of a softball. the "hairs" are about 1/4 in long (some of them anyways). thanks in advance

interesting...sorry i have no idea. some form of hydroid maybe

 

[katsafados]

YEAAAP
Hydroids.. you should be worried.. they sting.. and apparently they are hard to get rid of.

 

[tommy in jax]

uh oh.

 

[garick]

maybe somethin eats it?

 

[tommy in jax]

i was gonna grab a lawnmower blenny. if its hydroid, ide have to take out about 50 lbs of well established live rock and kill it all.

If you can find one a frilly nudibranch eats hydroids or the Alabster Nudibranch, "Dirona albolineata". However, I've never seen one for sale online but a person locally sells them. Unfortuneately I have lost their business card but still have the phone# PM me if you want it, its local to NE Texas

If not, you can take that rock out of the tank and use a new soft bristled brush and brush them off. Or wait for them to die off.

 

[tommy in jax]

this stuff isnt dying. its spreading.

 

[jaxfishgirl]

I am trying to find out what their food source is. Once that is gone they will die off....hopefully someone will also chime in

 

[katsafados]

he needs to ask cranberry or spanko..

i just got back from my LFS and saw the same stuff on several rocks on a few of their well established reef display tanks. this cant be something to be that worried about on my fowlr tank. i hope

Any chance you asked them what it was

Great....my tank is cycling. I have a few pieces of live rock and one of them has the same things on them!! I've done a couple of water changes to try to keep the critters alive and now I find out I should be trying to kill them!

BTY---JAXFishGirl---love your dog!! Is it a boxer? I'm on my 3rd boxer now and she is spoiled rotten. Sorry....off subject.

 

[tommy in jax]

yea, i asked them if they were hydroids. he said they could be. if they were, it wouldnt be a huge deal. sound right?

 

[cranberry]

Foraminiferans?
Hitchhikers
The forams are under sessile.... scroll down. Compare the pic to the right to what you have.

 

[tommy in jax]

ya, i could see that being it. looks a lil closer than the hydroids

 

[cranberry]

It doesn't look like hydroids to me.... I'm pretty certain it's forams. Harmless.
