Seriously though, larger tanks give you more water to dilute all the bad stuff with. People start wanting certain fish... regardless of tank size. Often the times, folks will start with a small tank because it seems easier, yet stock it to big tank levels, or with fish that want to really live in a bigger tank. The old "yellow tang in a 20g" syndrome. They get away with it for a while, but then wonder why after 6 months or so everything either died or was covered with algae.
All the books written by very knowledgeable people say the same thing: start with as big as tank as you can physically start with. While the amount of water in a small tank may make it seem like it's easier to keep, in the long run it isn't. Really. Small tanks (<20g) should really be reserved for folks that already have learned their lessons with bigger tanks and realize the challenge they're undertaking.
