My 2 cents
I'm no expert because I just started this hobby, but I would have to say... the bigger the better. After reading about all the different types of fish and their habits, put the largest tank that is possible in your home to house your fish. I have my girlfriend's betta in a 20 gallon long tank right now. It was in a 5 gallon square tank before. It survived about 2.5 years in that 5 gallon tank but once he got into the 20 gallon... he was a different fish. He is so alive and active it's really quite amazing.
On a side note, unless your home is so small you cannot place a 10 gallon tank anywhere, they are fairly cheap, small enough to fit in most places, and do not cost much to run. I was able to set up both of my 20 gallon tanks for about 200 dollars.
