Zoas growing on Zoas

[Blue04]

I bought a rock full of Green Protopalythoa polyps from my LFS a week ago and have noticed what seems to be a second mouth growing on another polyp. A few polyps have the same thing happening. Is it possible to have 1 polyp have 2 mouths or to have a polyp grow on another polyp? Thanks

Yes its possible to have 1 polyp with 2 mouths.
