For God's sake, don't expose life to any living creature in this drop of water. Beta are tropical fish. They need a heater and at least a gallon of water to live on (and a filter if you don't change the water every day). They can survive for a while just like you in small areas. Would you like to be cooped up in a 6 x 6 x 6 foot cube or do you want to live somewhere you can walk around?
