What's happening to this coral?

It's the only coral showing this. The rest of the sps and the clam are doing great.

Any help is appreciated.

Thanks in advance.

Looks like its browning out and some recession at the coral base. I'm sure some stick experts will chime in.

Hard to give an educated guess just by the photo. Please post your parameters and setup specs.

Looks like the SPS in the back are doing the same

The base is glue.... The sps has been for months in the tank. I see polyp extensions although not in the whole body.

The others are doing great.

Parameters are 400 Cal 1450 mag and 8 dkh

The first coral looks like tissue recession to me

I changed the location... Let's see how it goes

Looks like stress related to me. Newer corals still settling into a new system. Imo none of them look good but none look bad either. Just keep the big 3 stable and provide with with good flow and enough quality light and they will start to thrive.
