To fishtail?

I have yet to find the perfect long dress...I love the prints on this Tibi dress.  But what about the fishtail hem?  Even though my prom dress had a fishtail hem, I'm not a huge fan of the short in front and long in back.  If a dress does have a fishtail hem, I feel like it should be dramatic like a big bright tropical fish.  The hem on "Great Expectations" dress is more reminiscent of a muddy catfish.  At RueLaLa for 179.
