A 24" tall aquarium can sometimes be too much unless you have long arms and/or a step ladder. I really like the 36"x18" footprint.
Aqueon has a 50g that has a center brace like the 65g, but it is 18" tall with the same footprint.
A 40 breeder doesn't have a center brace and it is 16" tall with the same footprint.
I'm not trying to talk you out of getting a 65g, I just showing some options.
