Overview
The Betta is without a doubt, one of the most popular freshwater tropical fish. And it is easy to see why. The Betta is, first and foremost, brightly colored in shades of vibrant hues unparalleled among freshwater fish. Second, this member of the Belontiidae family is hardy when kept in ideal water parameters. Finally, despite their seemingly delicate beauty, Betta splendens requires simple care, which makes them a favorite of both beginning and advanced hobbyists.

Betta splendens is often referred to as Fighting Fish or "Siamese" Fighting Fish, since it has been bred over the years to be both colorful and combative, especially towards other males. As such, only one male Betta should be kept in an aquarium. However, smaller, shorter-finned - though often equally as colorful - females may be housed together with caution. The Betta should be housed with peaceful fish that will not nip at the Betta's glorious, flowing fins.

An ideal environment for the Betta is a well-filtered aquarium that holds a steady temperature of between 75° and 86°F. For best care, Betta splendens should be kept singly in aquariums of at least 1/4 gallon. It also prefers a variety of hiding places amongst the foliage of freshwater plants. Therefore, having an appropriately-sized aquarium with a filter and heater is essential for the proper care of these otherwise hardy and colorful freshwater aquarium fish.
