When I first took interest in starting a reef system, I was told by everyone I came into contact with that it was useless to have a reef tank less than 75ga. Each place I went to looking for a tank, I was being given different numbers. The lowest number was 29ga.
What was funny about the number games is that each place that I went to had nan cubes setup and running really successful. When I question them on it, each said that the nano cube didn't count and that I would not be successful with a nano cube.
I'm not sure if it was due to the fact they knew I was shopping for a tank and they just wanted to sell me the most expensive tank on the floor, or if it is what I have recently came to know that most LFS don't have a clue about saltwater aquariums. Honestly, there is no limit to the opinions you can get just by going to three different LFS and asking questions on which tank is better, which fish is better, which lights are better and/or which live rock you should use for your tank.
The conclusion that I have come to is that you must decided which is best for your situation. For instance, once I get my Masters degree in Accounting and Finance and I get a good paying accounting job and I can move out my mothers house and move into my own condo, then I can shop for a bigger reef tank. For now, I have to settle upon a 12g reef tank because that's about as big as I can fit into my already cramped bedroom. I live in my bedroom so I have everything but the bathroom and kitchen in my bedroom. My home office is in my bedroom. My surround sound is in my bedroom.

Anyway, I hope you understand where I'm trying to take this. Consider your situation and your long term goal and make your decision based upon what's best for you.
