ok, here is my 2 cents. its going to cost you twice as much as you can afford right now. that is because, unless you are VERY strict with your spending, you will always spend more than your initially budgeted. you will see the cool corals, beautiful fish, and latest and greatest in equipment. its very easy to go overboard in this hobby. second, i dont recommend going "small". "small" in this hobby is "difficult" at the least. the terms nano's and pico's should be left for the those with experience and a true understanding of saltwater husbandry. i recommend getting the largest tank that you can afford. the reason being is that, small tanks will go down hill fast and in hurry. if your not paying close attention, your $500-$1000 investment in a "small tank" will be disappointing. in a larger tank, its easier to compensate for things that may go wrong, and save the tank and its residents. first, read, read and read more. when you think you might have the faintest idea of whats going on in a saltwater tank, read it all over again. wish you the best of luck.
