Its great to see that you're researching how to properly care for a betta before buying a! Here are some of my thoughts and some additional information to help you make an informed decision and conciencios. The myth that Bettas prefer small bowls is just not true! Think of it this way. You are able to sleeping upright in a closet, but I bet you would not do that. Now imagine that your betta feels as if it were kept in an aquarium that was too small. Unfortunatley Bettas have no choice in what we choose to house them. The good news is that we control all aspects of the lives of our fish. What they eat, how clean their water is the amount of light, how much noise, what kind of decorations they have to live with and what size home they live in. Try five gallons aquarium filled about 3 / 4 of the way to the top with a screen cover like you could use for reptiles. Do not just take my word for that yet.
