my Betta is in a 2.5 gallon with a filter a heater and a light. and he has plenty of room. and the tank is sparkling clean. its a tall 2.5 gallon and i didn't put any decoration in it so he has plenty of room. i think if you are going to decorate your tank then you should compensate by getting a bigger one.
i personally don't care for the gumball thing but it seemed i did remember someone looking for one.
