plant

[FishFreak1961]

I have a plant that has appeared that has little runners on it and
little round dk green leaves, it sprouted from around my green
star polyps and I am afraid it is going to choke them out. It is
growing very fast and it feels like a rubber band, very flexible.
Good or bad stuff? Sorry for the bad photo, sorry camera
I have. Thanks for any input.

It is in the Caulerpa family. I saw it googling. My pic will not load.
Maybe it is not a bad thing. The leaves are round and it runs, but
I don't think it is the grape caulerpa, the leaves are flat round.
Food for inhabitants or danger?
