So I have my Halloween moon crab tanks next to my hermit crab tank, and at night it sounds like one of the three may be making chirping sounds. I assumed the hermit crabs were because I've heard of that before. However I was misting one of moon crabs enclosures today and I'm pretty sure the chirping sound was coming from there. Does anyone have any long term experience with these crabs because I can't find anything online about whether or not they chirp. Thanks in advance!
