What techniques can be used to train cephalopods? I noticed that due to spending less time in front off the tank my sepia hve become very shy and ink a lot. (why o why do we have to work?) I trained my murray eels, sharks and bullheads by tapping on the window and feeding them with long pliers, so they associate the tapping and the pliers with food. But I don' t think tapping the window is a good idea with sepia as they can hurt themselves by propelling themselves into the sides.
