Help?! What Is This?

I have all this purple hair SOMETHING growing on TOP of my live rocks. My tank has been running for about 2 months. I'm not exactly sure what it is, but my clownfish seem to love hanging out in there (i believe they are mistaking it for a BTA). I was assuming it is some sort of algae that is spreading through my tank. Can someone please tell me what this is? I have read up on some posts and it says that good water flow would prevent algae, but this purple hairlike THING seems to only grow where there IS good water flow. I've attached some pictues below.

Can someone please help!? Thanks!

Here are the pictures of the purple hairy things growing on top of my live rock.

 

Call me a weirdo but that looks like cyanobacteria.

 

what should I do to get rid of it? should I just pull it out? cut it? take the rock out and scrub it all off?

 

I would try to syphon as much as you can out, then take the rock out and give it a nice scrub (no soap of course ^^)

 

Can this cause my livestock diseases (ich, etc?) if they are always swimming in and around it. My clownfish lays in it in the night time like he is sleeping in it and I'm afraid if he keeps rubbing up against it, he's going to get some sort of disease. Am I just being paranoid?

 

Seems like ur clown has found something to host in.

 

You are a weirdo

 

Actually, and despite the fact that I have already called you a weirdo ( by your own request BTW ), I agree that it looks a lot like cyano.

Amcarrig, what's that other snotty stuff called? Dinoflagsomething or other?

If only all cyano could look nice, while fighting to get it out.
