Ronnie,
My general experience with shrimps and crawdads is that they molt.
When they molt, they are soft and vulnerable.
Killies are very fond of "soft-shell-crab" style dinner.
Only tanks with unusually-good hiding places tend to have survivors over any long period of time.
I just plain gave up, and decided to only keep such crustaceans in species tanks, and still provided good hiding crevices for the more cannibalistic crayfish.
