Elegance coral issue

[JustinMN18]

Hi everyone,

I have this elegance coral. It has been like this for a couple days.

Temp 77.5
Salt 35
Ammonia 0.2 (measured after feeding)
Nitrite 0.1
Nitrate 0
Calcium 480
Magnesium 1480
Phosphate 0.05
ALK 8.6
pH 8.2

Any ideas on what it could be?

Just to add, my tank is fallow right now. I ghost feed / clam stuff, aminos, and mysis for some of the inverts.

Lighting 2 Hydra 32hds, 55 gallon tank, 12 inches off the water.

I just looked at it, and I've noticed a pattern where it opens up more near the end of my light schedule. I'm wondering if it likes the less light. If it's closed up tomorrow, I'll move it to a shadier area.

Not certain but Guessing too much light. I have mine near the entrance of a cave where it is partially shaded.

Thats strange. Parameters seem good with MAG jus a tad high.
Personally, they prefer or I should say do best under moderate light and water flow , feedings 2-3X per week.
Temp range 77-79
salinity 1.025
CA 450
Mag 1300
alk 8-9
ph 8.1-8.3

I dont even feed mine and its the size of a football
