Do Platie's Sleep Much

My MM platy seems to sleep a lot at the bottom not moving or responding, I am thinking the worst as it has not woken up yet, but not floating.

Fish don't sleep. They rest, but never become totally unresponsive. I think that your platy is dead or dying.
 
fish sleep...any living thing would die without it. its when the body repairs itself and does the majority of growing.

since fish do not have eyelids, they literally turn off their eyes; their brain shuts off signals coming from their eyes when they fall asleep.

still, once you turn the lights on in your tank they should awaken. most of the time, even a small ammount of light will wake them up.
 
fish sleeping isnt the same as terrestrial animals sleeping. i read somewhere that fish will "turn off" only one eye while the other one is "on stand by" mode, ready for danger. basically, the side of the fish that they feel there's more of a threat of occuring, that side will have the eye on stand by mode. for example, if a fish is sleeping near an ornament, and its right side is facing the ornament, then the right eye will be turned off while the left eye will be minimally taking in information on their surroundings. i think that as a result of this, only half of their brain is asleep as well. also, fish need to be somewhat awake so that they can undulate their fins and stay upright.
 
Doesn't seem like much of an issue to me. Just stick a net in there and roust it. If it moves it's alive. Maybe dieing, but alive. If it doesn't move, it dead. remove it.
 
The real way to tell if a fish is dead is to look at its gills. If they are flapping, yet the fish is not moving, you have a problem with your fish. If the gills aren't moving, it is dead.
 
Fish "sleep" is not like the sleep which higher animals indulge in. Research is sketchy, but fish appear to be processing visual images but filtering them at a low level.
 
I had asked myself the same question if my fish ever slept. when I would turn on the lights, there they were swimming. But now I see that they do sleep.
