Basic Betta Info
The Tank - Your Betta's Home
Bettas are labyrinth fish, meaning they can breathe directly from the surface of water. Therefore they don't need air pumps to provide them with oxygen like most fish do. You often see bettas at pet stores in small bowls without any type of filtration at all, as bettas do not like fast currents (they come from small rice paddies). And most pet store employees advise their customers to keeps bettas in such small spaces because they seem "happier". How would you like it if you lived your entire life in a 2 x 3 ft room?Bettas need a minimum sized aquarium of two gallons. Although bettas can easily be kept in a two-gallon aquarium, the bigger the better - they would also appreciate the extra space. The larger the tank, the less frequent you'll have to execute water changes. Make sure the aquarium has lid or hood, as bettas are excellent jumpers.
