What's going on with my Zoas?

Hi there just curious if this is something for me to be concerned about.. here's a before pic, and then a more recent picture of my whamming watermelon. Notice how the center on a couple is now more of a green color.. why is this happening and do I need to worry?

Parameter changes will cause morphed coloration.

Also looks like a fairly new frag tank which may or may not be setup correctly.

Just taking guesses from the photo and lack of information pertaining to parameters from tank to tank.

Can the colors change back?

And yeah you're right it's a relatively new frag tank.. parameters are pretty stable except working on getting PO4 balanced, right now at 0.06 but has been anywhere from 0.0 to 0.25..

Yes they can change back.
