Question About My Fish!

[FLcracker94]

I'm sure some people ask the same question, and some allready know for sure, but I need to ask this...

My percula constantly swims in front of the powerhead at night, and I'm alsways scarred that she's going to get exuasted and stressed from not sleeping. But then I though, do fish really sleep?

So, my question is, for the sake of my clownfish...
Do fish accually sleep, or do they just hide?

If they accually sleep, I need to get a host for my clown so she will sleep. Sorry if this is a dumb question, and thanks in advcance.

Ok, I was just kinda worried cause at night, I see here swimmin in the current, and when I wake up, she's sleeping on her side lol. I allmost thought she was dead once.
