Do fish sleep?
my fish sleep all the time...I wonder why they never wake up....they just float on their sides on top of the tank....I try to wake them up to eat but no sucess...but it is saving me money on fish food....
Yes, my fish have there own spot they sleep in.
Fish cannot blink, but they can sleep to go into a power save mode
yes. but they dont close their eyes
Do the filter and aerator go off with a timer, or do the fish sleep through all the noise?
Yes fish can sleep
Yes they just don't shut there eyes
