Something growing on zoas

[Fishflakes]

Something is wrong with my zoa frag. There's some sort of black stalk growing out of one of the heads. Anyone know what this might be? My pics are horrible but I'm working with a cheap cellphone here.

Looks like sponge or tunicate.

Could be that too.

I know the pics are bad. It doesn't seem to move and it just popped up today. I dont think it's a snail. My zoas are not happy about it and they're not opening up like normal. I'm thinking about trying to remove it?

I just looked up pictures of them. It does kinda look like one I guess. I dip my corals, I guess this guy made it through? How can I remove this guy without killing the zoa? It's just a small frag, I'd hate to have to glue down on it.
