Caulerpa?

[graveyardworm]

This new macro just showed up in my tank, Im pretty sure its a caulerpa, just not sure which one. You can see in the pic its growing up in little whirls. I'm thinking maybe C. serrulata, but from the examples I've seen it doesnt grow up with curls.

I'm pretty sure your right. Mine curls as well.
