Can fish sleep? (and if so how do they do it)

Answers

Yes, fish can sleep! Fish do not have eyelids to close, so they sleep with their eyes open. Depending on the species, fish can sit on the floor of a bowl, for example, to sleep. Others drift close to the bottom.
Fish do sleep.

Knowing that they don't have eyelids (some sharks do) what they do is they "daydream".

Well, I know one thing that could help you with your answer.. snakes are more related to us than a worm because of it's sheddable skin. Even though snake skin sheds regularly and with a large quantity, they are similar because we shed our skin as well. Worms do not shed skin like us and snakes. Although, they are able to shed their tails to escape predators, like lizards.
