diamond tetra agression

Question
I purchased 5 diamond tetras 2 weeks ago (3 males/2 females) they are incredibly fast swimmers and they are becoming increasingly aggressive with the males chasing each other, the females and other fish.  I am trying to set up a 90 gal. community tank, have I made a bad choice? Will they settle down? Should I take 2 of the males back to the store?

Answer
Hi Don,
  I suspect that when you get them into the 90 gallon tank, things will calm down a little.  I can't guarantee it, but more space helps a lot.
