I have a blue freshwater lobster. I have had it about a year, and
during this time it has molted twice. During the last molt it lost one
claw. Will it grow back another claw in the future, or not?

I recall in the past I had another lobster, that during a molt came out
with no legs, and died thereafter. Do freshwater lobsters need low
levels of iodine in the water like sal****er crabs, and shellfish need
for successful molting?
