While they may be known by other names such as Bettas or Siamese, the Chinese Fighting Fish are most widely known by their beauty rather than their names. They are often chosen above all other fish as pets due to their appearance and the fact that they are inexpensive to keep.The small Betta is often seen displayed in pet stores and department stores in very small containers such as cups or even closed plastic bags. One must wonder when seeing these how the little fish can possibly survive in such “homes”. The fact is that, unlike most varieties of fish, bettas are members of a small group of fish called anabantoids, or fish with the ability to breathe air. They do so through the means of an organ similar to a lung. While many fish absorb the oxygen they require through the intake of water into their bodies, fish belonging to the group of anabantoids take in the oxygen directly from the air. When inhaled, the air circulates through their bodies via the bloodstream. This ability provides anabantoids such as the Chinese fighting fish or bettas the opportunity to remain alive for short periods out of the water.
