Fact of the Day: Do Fish Sleep?

Do fish sleep? Well the answer is yes and no. Most fish lack eyelids, and they certainly don't have beds. But they do enter stages of rest, and have been researched enough to notice problems like insomnia. Of course this varies between species of fish, but in short; your pet goldfish takes a nap way different than yourself.

  1. I sort of observe them in a relaxed state, but it must be some form of sleeping.

  6. Interesting fact, Adam. Well done. I don't have petfish anymore. Years ago we had a pond with fish in the living room. A lot of work, but very nice to see. Have a nice day. Greetings, Joke
