I am assuming you don't want to do saltwater since this is in the lounge. Setup a freshwater native tank. They are simple, easy to set up, water changes straight from the faucet and no heater needed. Plus collecting your own fish is fun.
Here is my 265. Everything was collected locally except the crayfish. 2 pumpkin seeds, 1 blue gill and 3 white catfish.
