because they do not close there eyes
No there not all fish sleep but most of them dont have eyelds therefor cannot close there eyes
fish dont have eyelids
the fish live in the freshwater...???? most fish dont sleep because if they stop moving, the oxygen does not get to their blood from the gills. they musty stay in motion to get water circulation inthrough the gills. if not, they die, such as sharks. other fish that do sleep just find a non-currented detritis-covered place and sleep.
Fish sleep on the ground.
i don't actually know how long they sleep but i do know that sometimes they sleep in the day. Right now mine is in a little area by my castle that i have in the tank. I don't think he's dead because he would be floating to the top. It is just weird though because the other ones are moving around frantically.
-Fish do not sleep -Fish do not have eyelids -Fish are very nice pets
i don't think fish sleep (the plural of fish is fish.)
Fish can sleep...and btw all fish have gills
haha good question....I have a fish myself and he seems to never sleep! But every now and then I will catch him in the corner of his tank moving back and forth slightly but remains in the same spot, this means that they are sleeping. Fish are never completley still when they sleep, and never close their eyes (if they even have eyelids....D: ) hahaha this is just a survival technique for them.....hope this helped :)
no. they dont eat while they are asleep. they only eat when they are awkae because if they eat when they are asleep, they might choke(?)
No penguins can sleep on water.
No. Fish actually only "rest" than sleep.
