High or Long aquariums?

which aquarium would better suit Molly's platys and danios? A high or long aquarium? I'm planning on getting a nice 29 gallon and I have the options of a tall and long aquarium!

 

Go for the long! Your chosen fish are not particularly tall and don't really need the height so they'll be happier with the extra swimming room

 

I think for those differently long. They need the swimming space

 

Thank you both! I just got it and I'm cycling it

 

Wow, that was quick! Pictures when it's set up please;D

 

Length and width are far more important than height.
