Is my torch coral dying? How can I bring it back?? Please help

[Bruen]

Please look at my torch coral.
It has deflated and drooping.
It was hosted by a pair of clowns but for the past two days I have moved it from the top of the tank to the bottom. Since then the clowns have left it alone.
It has been like this for about a week.
Normally it is a orange and blue colour but it has changed to a pale yellow.
My tank is 20 gallons. I also have a mushroom coral, and a grass type coral.

No just abit of moss or algae but it's not on the skeleton of the coral

This is a picture of it after it has been moved. It has inflated a little but the colour is still pale

this is what it use to look like. Last two week the clown fish which had hosted it had laid eggs underneath.

Has it improved since you moved it? What is the lighting and your parameters. It looks like mine whenever it poops
