Question : bleaching ?

[boumbo25]

Hi,
I dipped my zoa 2 weeks ago because I had nudibranches in it. Since then, I've put them back where they were, same light everything, but now, they are a bit yellow (more then what they actually look on the picture). Are they bleaching or something ?

Thank you,

Did you use peroxide?

Probably not bleaching. Zoas have a reputation for changing colors when you first put them in your tank. Mine look exactly the same but I have gone from 8 heads to over 30 heads
