Natural problems could cause a crab to feel fear, too. For instance, the humidity levels in the tank might not be appropriate, and this could make it tough for the hermit crab to breathe.
Chirping in response to being afraid of this situation seems natural. You should try to provide your crab with an environment where it can feel safe.
3 – Communication
There are times when hermit crabs start making these noises simply as a way to communicate. This can happen in several different ways.
Crab owners have spotted hermit crabs seemingly communicating with each other through chirps. This means that your crabs could just be talking to one another if they’re making these sounds without any other clear reason.
Sometimes a hermit crab might chirp as a way to call out for help, too. For example, a crab might get stuck on its back, or it might be getting attacked by another crab that wants to take its shell.

4 – Deterrence
Some people have seen hermit crabs make chirping noises when they’re trying to deter other hermit crabs. Hermit crabs will sometimes come into conflict with each other over various things.
It’s common for male hermit crabs to fight over mates. These creatures will also fight each other over shells that are coveted.
When a hermit crab wants a shell that is currently occupied by another crab, it’ll come up and start knocking on the shell. Essentially, this is how hermit crabs challenge each other to fights.
In response, the hermit crab that’s inside the shell will begin vibrating. This will create a chirping noise that is meant to show the other crab how strong an opponent it is about to face in battle.
In some cases, the chirping might scare off the invading hermit crab. Other times, the hermit crab might step out of the shell and actually battle the invading crab.
5 – Aggression
After reading the above information, it shouldn’t come as a surprise that chirping could indicate aggression. Sometimes chirping will be an aggressive response to a situation.
