DO FISH GO TO SLEEP?
YES, FISH NEED TO REST JUST LIKE PEOPLE. IF YOU SEE A GOLDFISH LYING QUIETLY AT THE BOTTOM OF ITS TANK IT MAY BE SLEEPING. BUT IT IS HARD TO TELL, AS FISH DO NOT HAVE EYELIDS AND THEY CAN'T CLOSE THEIR EYES THE WAY WE DO. SOME FISH, SUCH AS THE LOACH, SLEEP IN THE DAYTIME AND MOVE AROUND DURING THE NIGHT.
