I’m not sure what exactly it is, but I’m also not sure it is showing its “true colors”. It kind if looks like it may be browning out, possibly from excess phosphate. Mine did that when my phosphate was super high and then brightened up and showed more color once corrected.
Coral can brown out just because it got moved yesterday also. Don't put much weight on a new specimen Browning on anything else but being moved. Way to early to tell.
