Changing color or hybridizing?

[Kimberely]

I have 2 zoa colonies that consist of radioactive dragon eyes and wham'n watermelon. I noticed these tonight and not sure if they're new or just morphing. They have green skirts, blue discs with a bright yellow center. Can they morph that much or are they possibly a hybrid of the 2 mother colonies?

Did your zoas come on a small frag plug or a rock with multiple zoas already growing? Many times when they collect zoas from the wild they often have another type of zoa mixed in.

They came on a rock. I've had these for over a year though and these just appeared recently.

My guess is they were small and unhappy but are now just getting use to the tank and making an appearance.
