I have been keeping crayfish lately. (there are a lot of the
introduced P clarkii here, they are considered a pest) Crayfish are
_extremely_ cannibalistic. I've had the same experience with other
species too. Anyway, they will attack one another anytime they are
too close, but particularly after molting, the soft one will be
devoured or mutilated by his compatriots. They are absolutely
merciless. The same is true of freshwater shrimps. This may be the
cause of your "loss of limb" :) On another note, crayfish and
shrimps should have a good vegetable component to their diet. I
haven't discovered the best source of this type of food though. They
will usually ravage any live plants that are in their tank. A lack
of vegetable matter may be the cause of some crayfishes turning
blueish in cativity.
