Help with my favia coral

[Michaelbknudsen]

Had this about two weeks. Placement was high at first until the too of the coral started bleaching I think?! Moved it lower in the tank, but just curious if any would could chime in and help me out. Parameters are all great in the tank, and everything else is thriving. Lighting is 4x24 t5 HO over a 20g long.

I keep all my favias on the sandbed.
I would try that.

You usually syaty low and then go high with corals by the way. But this one stays on the sand anyways
