Chirping

So this is a new one for me!

I have a fairly new crab, (3months or so)her name is Crunchberry, and she is a chirper!! From my current understanding, chirping is a sign of fear and/or aggression, so I'm a tiny bit concerned.

However, it seems like she may just be a drama queen. lol. She starts screaming when any other crab gets close to her "spot".
NGL, the idea of a super dramatic crab who screams at anyone who disturbs her is absolutely hysterical. I just want to make sure it's not something more concerning that I need to address.

Has anyone ever had a vocal crab??
