i never tap the glass either. usually the fish come up toward the surface and follow me around the second i get close to the tank. And when the lid opens they go nuts and get ready for feeding time.
It's pretty reassuring that your fish are happy and stressfree when your rummies come up and act like african cichlids during feeding time.
