Is this a zoa or just a polyp?

[rubysmomma1]

Not a very good pic. This hitchhiked into our tank with the new LR in September. I'm not sure if it's a zoas or just a polyp. There are probably 20 heads now. I'll get a more recent pic soon, but if I could get help through this pic I would appreciate it.

Thanks!

a large type of polyps, not a zoanthid, but nice nonentheless.

Looks like a green button polyp/Protopalythoa

Yeah, that looks like a Palythoa polyp (or what is/was Protopalythoa). One other comment - both Palythoa and Zoanthus are zoanthids - all animals in this group are. Confused me to bits when I first started studying these things...

Still can't keep it straight now after reading your thread on the new taxonomy. lol
