I have been looking at the 12gal and 22gal cubes. The ones that they have in River City Aquatics here in Austin are beautiful...the coral is amazing!! I want to start of with coral/live rock and build from there. Probably put a little clown in but am not focused or thinking about fish just yet.

As for budget...well, like anyone I don't want to spend boat loads of money. I figure that if I can keep the total purchase/initial set up cost under $500 that would be great!!! I have found a couple of CAD cubes online that range from $169 (12gal) to $219 (22gal) and include lights and a sump. Not sure what else I need to purchase and what can be used from our existing tank.
