What is this grass-like plant?

I bought a small zoa frag about a week ago and there is a small tuff of "grass" growing out from in between the zoas. It looks like it is growing, and I'm not sure what it is. Do you guys know what it is? Is it harmful to the tank or the zoas? If so, how should I get rid/take care of it? Thanks for all of your help.

 

turf algae? could really use a pic, there are probably thousands of possibilities.

 

I'll grab a shot now. I'm just being lazy... lol

 

Ok, so the picture isn't uploading for some reason. It looks exactly like small grass about 1/2" tall. Very green.

 

google turf algae or hair algae

 

no pic, no ID. It's just not possible from your description alone.

Try using a photo hosting site like photobucket and copy/paste the pics url to your post.

 

Could be gsp. That is quite grass looking.

 

Try photobucket.

Copy and past the IMG code, that you see when you click on you image, paste the IMG code into your post or thread.
