In a sense, they do. If you watch a betta, you'll notice times where the betta will go still and not move. This is where they 'shut down', and it's only for a short amount of time. They don't 'sleep' as we mammals do, but that's how they get their rest.
well it is kind of like sleeping but they close one eye and leave the other open in case somthing trys to eat it
Betta dish actually don't sleep, or they'd die.

No. Bettas sleep a lot. It's good for them
