Is your tank grounded? Elecrical "noise" will stress fish out, especially
newcomers.

I really had to pull on it to get it unweged. It was
really strange. I've never seen anything like it. It's almost like the
fish committed suicide. The carcass showed no signs of disease and he
ate
fine earlier that night.

Did you move rocks that night?

The fish was dead but it showed no signs of disease or trauma.

How did you tell the fish was dead? Was it disintegrating?
Are you sure you have not taken out a normal, healthy fish?

Does anyone have any ideas on why these fish seem to be acting
this way to cause them to die?

"Acting this way" is NORMAL for royal gramma and other similar
fish - when stressed by you, aquarist, or by other, bigger fish,
they seek hideout in a rock crevices and wedge themselves
head first... Somtimes the tail sticks out, sometimes not...
Sometimes fish curls itself to stick to the rock best.
All to not get any chance of larger predator to scoop it out.
It usually ventures during eveing, right after the lights
go out and other, bigger fish go to sleep...
