How much light does your living room recieve? The more light, the wider range of possibilities. The list, as far as indoor bonsai go, is near limitless, and new bonsais are always being "added". But, if you want to go with the beaten path, I'd recommend either Schefflera arboricala, or Ficus retusa. These recommendations are made not knowing the level of light in your living room (they can survive about 200-250 footcandles). But, if you have more light, thats better, because you can grow a wider range of indoor bonsai.
