Answer 1

They are more ommonly referred to as nano tanks. You can buy complete kits for around the $200-$300.00 range depending on the size. They will have the ability to keep a variety of sea life in them. Here are some sites for you to scan through.

Answer 2

Are you talking about a salt water set up? And how small? The smaller the tank, the harder it is to maintain the tank. Usually it's recommended to do at least a 55 gallon if possible, but expensive. Here's some links to search.
