It's my experience that Vics like room to roam. I think you are much better going with a tank that is wide as opposed to deep or tall. I think a 75g long is the perfect Vic tank!
dirk, thanks! i just saw you answered... problem i'm dealing with now is the room for a long tank.. thats why i was looking into a hex, column, or pent... so i guess the longest of the 3 if need be will be best ...hrmmmmm
