how long do crawfish molt
Since then (about 5 months), the crayfish has molted 3 additional times, all overnight. It's now up to about 7 inches, and hasn't molted in about 3 months. I found that when it had a supply of live fish to eat (darn!), he molted quite frequently. Since I've moved the cray into it's own 10G, he hasn't molted at all.
