Do clown fish ever sleep?

i have two clowns in my 100gal, the fish are probably aboutan inch or two in size there only babies but i never see them sleep ever time i come in the room without the lights on there still flapping about like mad, and how come they never take cover in the rocks??

My maroon clown hides behind the heater at night, I guess that is where he sleeps.

 

mine goto the area of the tank that has limited movement and they just do lil motions every now and then whey they start to float up.. but that's their sleeping spot.

 

My maroon clown sleeps in his anemone at night. He wriggles around but doesn't come out until the lights turn on in the morning. My lawnmower blenny actually sleeps in the zoas as they fold up for the night - the damsels hide in the rocks.

 

My maroon builds a next every night, about two hours before the lights go off she starts moving substrate around by pushing large pieces or picking them up one by one with her mouth and placing them elsewhere.

In my other tank my Clarkii sleeps in the seabe and doesn't come out until I turn the TV or a lamp on in the morning.

 

i have a pair of percs and 1 saddleback clown and they all sleep in my seabae anemone
yes they do get along because i introduced the 3 of them together, and the pers have paired and still tend to leave the black saddleback alone

 

maybe i need a seabae nem

 

If you get one they are usually white, and that is not good, make sure you feed it often for the first couple months. When the zooanthelle starts becoming more plentiful it will start to brown and that's a good sign. Many people don't have good luck with seabes and not getting them healthy in the beginning is a major cause of it.

 

Sleep no fish don't sleep like us, but they do go through periods of inactivity at night.

 

is there a sort of minimum length of time your tank shouls be set up before getting a nem??
