I was just wanting to hear from more experienced Zoanthid growers. I have some Zoas that I put in a few weeks ago. They seem to be doing fine but the color is not exactly what is shown in the pictures (WYSIWYG). The main thing is the center, the mouth, is not the color it shows. Will they eventually return to that color or is something missing?

For instance I have a deep green that is supposed to have a blue center but it is pretty grey right now.
