White pompom xenia not so white anymore

[fishguy2727]

My white pompom xenia seems to be getting darker and darker. Anyone know of any reason for this?

My guess would be that since it is up so high with good lighting and the water quality is very good that maybe there are more zooxanthellae to take advantage of the light since there isn't much in the water to use for energy. Zooxanthellae is brown, so more zooxanthellae means browner xenia. My concern is it may be instead or in addition a LOSS of white pigment.

What do you guys think?

My Pom Pom Xenia is usually pretty pinkish when it is doing well.

You are right, it is from the zoanthellae. If you don't like the look, move it down.

That is what I thought, and what I was going to try if I didn't get an answer. Thanks.

In my tank, the whitest are in really bright places. Directly under 250 halides.
