algae ID please

i got these zoas and on the rubble it is attached to there is some type of algae. Can u ID it please? i want to know if it is a problem and would it spread around my tank.

 

I can't see it well enough to help. Can you get a clearer pic?

 

ok I'll go try now

 

Ok i got these. hopefully they are better.

 

Well those are better but I still can't help you..sorry. This may be of some help until some one else chimes in.
trial page, algae ID

 

try to describe it, is it jelly like? is it crusty? is it all over or just there? i wont be able to ID it but with a lil more description im sure someone will

 

well it looks just like moss that grows on trees, just a slightly different green and it's just on the piece i got it on. it moves with the flow, so it's soft.

 

the tenth pic on the right is the closest but i'm not sure
