Possibilities:
New bulbs or spectrum changed.
Recent use of GAC or GFO sometimes could trick that.
Lack of water changes or food particles/ additives, like amino acids, traces and vitamins.

Most of the time not a big deal.

Hola. Do you happen to have a picture of the bleached skirts? Did your different zoas happen to lose the color all at the same time? Only time I had a zoa bleach was when I didn't properly light acclimate them. What type of lights do you have and how long have you had the polyps?

I think he is talking about the skirts only, not the usual bleaching per say.
It's just an adaptation (morphing) and wouldn't be related to a shock, leading any type of real bleaching...
Note that he stated the centers all having good colors.

Yeah but I have talked to people who said they had amazing zoas only to see they were bleaching and the colors were a lighter neon color in the middle. I am not saying this is the case here but this is where a picture would be most useful.

So we can rule out bleaching without anymore info and pictures?

how long have they been in the tank? if they are newer and looked different in a different tank, it could be just how they will settle into your tank. Zoas always look different in someone elses tank
