hybrid zoas?

[Saddler]

I'm trying to figure out if the zoas in the upper-middle of this photo are hybrids:




There's more info. in this thread from my local reefer group:

Not sure, but you can definitely make an argument that they might be.

Take a polyp of each and mount them. See if it happens again.

I had some with blue centers that sorta did that. I mounted one polyp on a small rock and the second polyp that grew had alot better blue color to it and a yellow spot in the center. Didn't look alot like the first, but I guess since it had grown in someone else's tank with different lighting, flow, parameters, it turned out looking different.
