Is there a general guideline that helps with determining if a rarely kept species is diurnal or nocturnal on advance? Do nocturnal species have any advantages that diurnal crabs lack? Two crab species I'm interested in are Discoplax magna and Perisesarma eumolpe. In my understanding the former is nocturnal and the latter diurnal.
