Something happened to a few Zoas

[GoodAfternoon]

I have some zoas that went from having lime green on their skirts to their middle part. This happened very fast over 2 days. They have been under the same light for a while now. The color change is spreading and I would like to know if this is healthy, and if I should try to move my coral to lower light.

Seems odd that you would notice a coloration change so quickly if it was lighting related. Have you done any testing for N/P.

They look healthy.

That is quite fast. Lighting could be affecting them though, I know when my utter chaos were higher up in my tank getting pretty high lighting, they turned completely orange, lost the dark specks on the base and lashes. Theyre now lower down the tank and are getting back their dark specks

Nitrate is almost undetectable about .2 and I don’t have a phosphate kit

I think they may be getting too much light then. Oof
