Do Goldfish Sleep?

I was watching my tank from afar shortly before the lights turned on this morning and one of my goldfish the early riser I guess was awake and swimming then the other one was laying down in the corner. They're different species. As soon the light turned on the other one "woke up" and began swimming normally. Do they just sleep? My water parameters are all normal I take good care of my tank and water change with a python.

 

Yes they do!!

 

All animals sleep...if they don't sleep they become lethargic and miss deadlines, just like us **** sapiens.

Usually they just float around in one area.

 

I have a eel that hangs over stuff while sleeping like its hanging on a coat rack.

 

Good to know it's a regular thing so I shouldn't worry

 

Was it laying on the bottom of the tank? Because that's not normal for goldfish. When they sleep, they just move very little, and their fins move to keep them above the substrate but about in the same place

 

Mine sleep flat on the subtrate. You'd think they were dead. lol

 

It never touches the substrate and it happens every day during the night hours.

 

Oh that's totally fine, weird to see at first, isn't it, lol

 

They don't have eyelids so it looks like they are awake but the motionless movement will let you know they are sleeping.

 

Makes sense it's weird after your tank is well established I never noticed it
