Why are my cories I just added to my tank skimming the glass all over?

One of my cories just does laps around the glass at the mid level until the lights go off. It is a mad bit of swimming madness
 
I have 6 cories in my 55 gal now and they give me no end of enjoyment during commercials. Usually once one starts swimming up and down and around the glass they all join in, I love it :)
 
maybe the new cory is trying to figure out a way to get over to the couch to sit and watch some TV?

One of mine took a few days to settle in enough to relax (as relaxed as cory's get anyway) His days of 90 m.p.h. laps around the tank are over.

Just make sure that in his laps that he isn't trying to rub on decorations and such, that behavior could indicate a parasite.
 
cories are amazing! My mom had about 3 in her hex (a big hex!) and the littlest one always ran up and down the glass at about 70 K ph and flew out of the water and smacked the glass hood! he sometimes did this for hours!
