Dying cories -- please help!

Zanytomato - how long between the time you bought them and they died? The cories I just bought showed no signs of anything. One thing I did think was that they looked thin. There's no ick, no flashing, no fungus, but these also aren't active at all.
 
Hi Debbi,

They were just about a month old. Looked in great health. One was especially beautiful -- his stripes were amazingly perfect!
