Zoa's spreading out every where??

[rdlisby]

I have some green Zoas in my tank they don't look like anything special, but they don't "grow together" in a big clump like I see in a lot of pictures. I have them growing all over in my tank and once one takes hold they start multiplying and spreading. Any thoughts?

Chances are it is a palythoa, they do not typically have a mat that keeps them bunched together as closely as zoanthids.
