I assume when you say "rasbodas" you mean "rasboras"? In that case, based on the nature of the poll, I voted for them, but I also am partial to anabantoids.
No room, Sir Minion?!? A good fish keeper never says they don't have room for more fish! Get rid of the TV. Get rid of the couch. Get rid of the dinner table. If you need seats that bad, then plop bean bag chairs in the floor.... in front of your brand new tank and puffers! No room... For shame!
I love catfish, and have 10 that I can think of right off the top of my head.
My fave fish are Endler Live Bearers. Have about 15 + lots of fry. I just love them as they are so colourful and easy to keep. They are also really small so I can keep lots.
