I've had these sitting at the bottom of my tank for 4 years now, one came on a piece of live rock and grew everywhere. Always wanted to know if it actually had a name. The pic was taken with all whites on. The center is a rust color with a faded green outer rim..
Those are pretty cool looking palys. It's rare that palys actually get that kind of patterning. It looks kinda like gold maul, but mauls are zoas not palys and based on the debris incorporated into the stalks, it seems that these are in fact palys.
