Palys loosing color

[jwoyshnar]

Hi all. Some of my palys have lost some color. My greens aren't as green as they use to be. Is there any trick or something I should know?
Thanks

Hey a picture would be a huge help. How long have you had the zoas, what sort of lighting are they under, have you moved them at all recently, any major changes to the tank?

Usually when zoas bleach (lose color) it is because of too intense light. But without pictures it is pretty hard to tell.

May be the bulbs are too strong or they are getting old.
