5 gallon tank= a good betta tank with live plants. Your betta will display beautiful swimming, flaring and exploring behavior in these larger tanks that you may not see when they are kept in smaller habitats.
Saw a gorgeous tank w/Neon Tetras & had to find out more. Love the background of these piece of art: Aqua Bonsai is a creative living art of micro aqua landscape in a vase or container with an abundance of aquatic plants. By using the natural ecosystem to maintain its life, it shows the harmony of living things. No air pump needed as the plants give off oxygen- it's just so peaceful! aquabonzai.com
