Need help with an ID no pic available BANG GUY THIS MAY BE FOR YOU?

My local lfs has a rock with what appears to be yellow zoos on it, I already have the yellow polyps, so I know what they look like, the thing is these look as though they could either be nice yellow zoos or yellow polyps that have not been taken care of. I need to know if you can tell a physical difference in the two, whether it be tentacle number, or what ever.

Squirt some food at them like frozen brine or Cyclop-eeze. The food will stick quickly to Yellow Polyps but will drift away from Zoanthids.

Aren't yellow polyps also a lot longer and frillyer than yellow zoas?
