"If you want to set up an artemia colony (aka "sea monkeys"), this is a fun place to put and display them. If you want to house a betta, this tank is absolutely no good. Do even a little research, and you'll soon discover that bettas need more space, filtratrion (or absolutely DAILY water changes), and heat (uinless the room is at aconstant 76-78 degrees Fahrenheit). Plus, if you get at least a 5 gallon tank (doesn't take up much space) you can put a lot of nice plants and a snail or some shrimp in with Mr. Betta."
