In our 75 gal tank, we have one plec, Bigfoot. Occasionally when he is
cleaning, he will dart up to the surface and back down for no appearant
reason. It almost looks like he is going for a breath, but he does it
so fast I just don't know what to think.

Is this normal Plec behavior, or is he just having fun?

I had one that did that every nite as part of his waking activities. Bounce
off the bottom of the glass cover, then do a fast circuit around the tank
before beginning his daily turning the substrate over and etc. He'd scare
people, a 12" pleco can make quite a splash.
