Is it normal for BTA's to close up at night? It doesn't completely close up, but gets much smaller and only leaves a small group of tentacles out.

It is kind of sad.... my clowns try to sleep on it, but have trouble fitting on it.

Anemones will open and close up based on the amount of light that is available to them. The ones in my tank tend to close up and are appox. 1/3 their normal size at night time. Once the metal halides come on, they fully open up.
 
mine is under T5s all day and it closes up just enough for the the clowns to sleep in it.. well only one really lol still its closes at night none the less
 
Mine tend to stay the same size 24/7. I only see them shrink when they are pooping. Other then that they stay open all the time.
