Damsels do sleep...you seriously think that when you put a damsel in with an eel that its life wouldnt be on a timer?
Personally I would never stock an aquarium with fish that I KNEW were going to die sooner or later from predation unless they were intended as feeder fish. If you want to waste money using damsels as feeders. Go ahead.
