2-3 foot tanks are good. I wouldnt go angelfish they are very agressive i heard one lady had one in with a black moor and it ate the black moor's eye, so she flushed it. you could have neon tetras, rummy nose tetras, head and tal light tetras, rosy barbs, white clouds but if you after something bigger why not guppies ( you can get very nice fancy male guppies) with plants and orniments. Or you can have a group of female fighters. its really up to you but try and pick same size fish or something that wont over grow. (bristle nose catfish also coz they eat left overs and poo) and are cute. when you buy ask what size they grow if they dont know go some where else.
