My Fish Wont Sleep!

[Florida_Fin]

I am a new aquarium hobbyist and I have had 3 wonderful zebra danios for about two weeks now. They seem to be the happiest fish in the world...just one problem.
They never sleep. I have woken up at 2am, 7am, 12pm, etc, and it doesnt matter if the lights are on or off, they are still swimming and chasing each other around the tank.

this is really stressing me out because I just want to know they are getting their good nights rest.
any advice?

Not all fish "sleep", and certainly not like we do. Its hard to sleep when you have no freaking eyelids!

They will sometimes settle on the bottom, some do a strange headstand in the water, but as long as they're getting a good 12 hour lights out period, they'll be fine
