one my RCS died..

I have tested my water and its perfectly fine.
my temp is 80 degrees.
I don't have any fish that is a threat.
I feed them regularly.
I've had them for atleast a month now.
So what could be another reason why one died?

It could be old age but I'd do a PWC just to be safe. Are you certain its not a molt?

Its a pfr and its pretty red so I'm sure its not unless it comes off that red.
And could be... Cause I see a lot of my shrimps either saddled or pregnant.
