A friend gave me this rock with an almost white Zoa after I commented on it in his tank. He did not know what type of Zoa it is. I am trying to identify it and also identify what causes the color to shift from what ithe blue/green/brown to the blue/white beneath it. I am told they are all the same Zoanthid species. Since they are on the same rock, I wouldn't think it is nutrients. They were getting about the same amount of light, so it doesn't make sense to me.
Thanks,
Ashley
