Article: There is a lot to know about betta fish, even beyond the basics just outlined. In general, large box stores aren't in the business of providing detailed information, unless you happen to strike a betta enthusiast salesperson. As well as having the basic understanding of betta outlined above, you might consider researching more details about betta fish online at specialist sites. These sites will remain useful for you after purchase too, as you'll be able to ask questions, check up health and nutrition notes and find like-minded betta fans to share stories with. Please be aware of what you are getting into before you buy a betta fish. Know that these fish can live up to five years under the proper care, so do your research before buying. The minimum size tank for a betta fish is 2.5 gallons with a heater and filter, although if you have a bigger tank, you don't have to do as many water changes. Despite the recent fad of keeping bettas in small vases or bowls please do not keep a betta fish in a tank or bowl that holds less than 2 gallons; it is terrible for their health and is very small! Remember that even though these fish may look like flowery decorations, they are live animals that need room to swim around and space on the surface of the water to breathe and eat.  Your betta fish will not be happy or live as long if kept in these small places. The best room for a betta tank is one that is calm, quiet, and off-limits to pets that are a risk to bettas, such as dogs or cats.  The tank should be placed on a sturdy, level surface to prevent the tank from spilling over, and there should be outlets nearby to plug the heaters and filters into.  The tank should be away from things like windows, vents, doors, or humidifiers, as the temperature fluctuations and UV exposure can pose a danger to the health of your betta, and encourage harmful algae growth in your tank.
