Are Hermit Crabs Nocturnal??????
This is actually a question I’m not 100% sure of the answer. My hermit crabs are not nocturnal. They are up and about all day. My small PP, however, sits inside her cocohut all day, only to come out a few times. I might say my smaller crabs are more nocturnal than my larger ones. When they are all up, my larger ones are ripping up the tank day in and day out.
