I've got my only betta in a 5 (UK) gal tank all by himself and he certainly covers the tank. He loves going wandering and poking into hidey holes and generally enjoying the space to swim about and explore.
I know that most folks keep them in smaller tanks, but I love seeing mine swimming languidly from one area to another - you get such a good view of him.
