Simple Aquarium by aquariadise: 5 gallon tank: good betta tank. 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.
Bettas are completely underrated. Beautiful, tough, and often full of personality. Whenever someone asks me about what fish to buy as a beginner fishkeeper I ALWAYS recommend bettas. Probably my all-time favorite type of freshwater fish.
