I have had fish before whenever I was younger and I was just wondernig if they sleep..because I don't ever remember seeing them sleep before...but who knows..and I ask a few people as a joke and they said they had never saw a fish sleep before so they didn't think that they did sleep...and I was thinking I dont think that fish sleep...do they?

I looked this up since I was curious. Evidently, they rest (they don't have eyelids to close) and it's more of a daydream like state than our sleep state. So they are motionless and the term would more correctly be "resting" since they are alert to danger during this time. Some fish can stay motionless, while other fish such as a shark, have to remain in motion to stay alive. They either have to swim or maybe stay in a current to keep moving. whit

Yes I do believe they do sleep. I think they sleep with their eyes open. You know they are asleep because they don't move when they are sleeping and they huddle down close to the bottom. Now don't ask me how I know this, I just do. I must have read it somewhere or heard it or something.
