Looking for torch coral guidance

[Pico Perfect]

I have 3 torches in my reef tank. Until recently, all 3 looked good, opened well and had vibrant color. The first picture shows all three corals.

Picture 2 shows how the torches are typically open with active tentacles flowing in the current.

For the last few weeks, my Aussie gold tentacles lay flat and the color just hasn't been there. See picture 3.

I'm wondering what may be causing this one torch to be suddenly less vibrant than the others.

How close is that xenia to it?

About 2.5 inches

Last image looks bleached a bit - try lowering it, giving it an amino bath and also antibiotics such as furan 2, cipro or even h2O2 wouldn't hurt - aussies are tricky

I think you are right on the bleaching look. It was higher in the tank, but I lowered it before these pictures were taken.

I think I may borrow a par meter from my lfs and check the areas in my tank. Have not done that yet.
