What's growing on my zoa colony

Can anyone tell me what this green and white slime is and weather or not/ how to get rid of it.

And the white

Could be a sponge or tunicate...hard to tell with picture not in water

 

[jtaylor1101]

Should I worry about it

Well if it was a sponge, it will die off soon if you left in the air for longer than a minute.
You can try a manual removal if you want.
I have a sponge growing in one of my colonies and I have just left it.
