Is there anything wrong with a corner tank?

[tony_3a]

I have the fluval osaka 260 and i realized it just wont work for a salt water tank. So i called the place i bought it from and they will let me exchange it for another tank, only problem is all they have left is a fluval corner tank 77 gallon. But it is drilled and it will work fine im assuming. I know lighting will be a problem if i want to do reef. Other than that is there anything i should know about corner tanks?

Thanks a lot
Tony
