My corys did the spastic elevator dance from time to time - mainly when they were young. Always amusing wondering when they'd tire out after having been at it for 8+ hours. They're currently several months older, healthy, fat, and seem quite happy.
My dempseys rove around in a pack. They seem to enjoy the top of the tank at night. When they're pissed off about not getting crickets / convict fry, they'll spend all night biting the surface - making nice loud snapping noises to prove they're not going anywhere. -_-
