Zoa

[Tuskdomer]

I put this zoa in 3 weeks ago. It is open, but lost all color - bleached?

Anything I should do? Fluval reef light. All chemistry normal.

Fluval lights are rather weak for a reef light, the size of the discs and length of the stalk tell me they are reaching for light in a sense, or at least trying to get in as much as possible. I would move them closer to the light and see how well they do.

If your tank has really low, or even undetectable nutrients, it can also cause this sort of thing in zoas. Do you by chance know where your parameters are at?

They look like parazoanthus so they might remain that color or get a yellowish shade.
