Dead albino corey.... any ideas?

The female platies are no doubt the largest fish in my tank. I've noticed that the platies will push the cories out of the way when I'm trying to feed them their sinking pellets.

that is a likely issue then... maybe one of the cories got a bit too close to a shrimp pellet lol...

sorry for your loss

and again keep infection in mind as a possibility as well
 
The red colouring looks like an internal haemorrhage, but that could be post mortem.
