When Crayfish Molts?

Crayfish need to shed their shell now and then, periodically. The outer layer does not grow while their insides grow bigger. That is why they molt. In the first year, they molt up to 6-10 times, and it slows down as they age. The key symptoms are:

• Spending all day in the burrow
• Feeding is avoided
• Comparatively inactive and also motionless.

Before the exhausting period, they need to conserve energy, and during the process of exhausting, they will seem to be ill. The molting process can take minutes to hours to complete.

The molting period is very sensitive for the crayfish as they are unprotected without their shells. The hunter becomes the prey, and the unthreatening fish becomes their predator. Even the crayfish could be a threat to each other if either one were molting.

As the crayfish mainly stay in their burrows while they molt, there is not much you can do while they are molting. But if you are concerned, then you can keep the other fishes in another tank. But the important thing for you to see is that while the crayfish molts, the temperature, pH, ammonia, and nitrate levels are at the right level.
