it might not work well in a standard-dimension 75g...remember bettas get 90% of their oxygen from the air, and too deep of a tank will leave them unable to comfortably use a good bit of the water in it...i could see it being good as a sorority/community though, with a school of some smaller catfish like cories or synodontis at the bottom, some tetras or platies in midwater and the bettas in the top. you'd have to choose plants and scaping carefully though, to provide cover at all depths.
