Zoas changing color?

[nate213]

I have a small colony of Zoas (not sure of the name) but they are normally all purple. In the last couple of days 4 of the polyps have changed from purple to green. They now glow brightly under the actinics. Is this is a good thing, or something to worry about?

should be ok most corals will change color in diff light. Maybe your light "better" for them. Or could be caused by water chem too. Usually a change to a "brighter" color isn't a bad thing

. Some pics would be nice

zoas are notorious for morhing depending on light flow and tank conditions. you may not know for sure what they are going to be until they completely finish changing to the new forms.

i agree with the others, some pieces can morph depending on lighting/placement/water conditions. before and after pics would def. be cool!

Here are the photos. As you can see the polyps toward the bottom right are a turning a greenish color. None of the others glow under the actinics.

they are in the process of morphing just take some time for them to completely change. some of the colony could stay the color it is and some will continue to change.
just watch in amazment as they do LOL

Thanks. That is good to know. I was worried there was something wrong.
