How does crayfish molting occur?

Molting. Molting is usually accomplished in minutes. The brittle exoskeleton splits between the carapace (head) and abdomen (tail) on the back side, and the crawfish usually withdraws by tail flipping. During the “soft” phase that follows, the soft exoskeleton expands to its new, larger dimensions.

Use conditioned tap water, spring water, or well water. The water should cover the back of the animal, and needs to be no more than 15 cm (6″) deep. If kept in deep water, crayfish can deplete the oxygen near the bottom. Since they cannot easily swim to the surface for air, they may suffocate.
