The main advantage of these fighting fish is that they can live without oxygen and filter. The fact that bettas breathe atmospheric air. Moreover, they even do not like to live in an aquarium equipped with a filter, as such housing is oversaturated with oxygen, and the flow generated by the compressor, only scares them. Of course this is not to say that bettas can live in three-liter jar, but the fact that they thrive in a small aquarium without any filtration and aeration, it is an undeniable fact!
That's just the breeding of these fish can cause some difficulties, and not everyone wants to become a professional breeder. Many people generally contain males for enjoying their beauty. Not whimsical chickens and the rest of the service: they thrive in stale water, and do not have an increased appetite. However, this does not mean that bettas water needs to be changed every six months and feed them once a week. No!
Aquarium fish betta (or bettas) are members of the family labyrinth. These fish casually dubbed the "roosters". The fact that their color and warlike fighting spirit reminiscent of the beautiful and cocky cocks.

Length calf males 5 cm and females – 4 cm across or Along the body of males are dark bands. The top fin has a rounded shape. Lower starts from head and goes to the tail. The pectoral fins of males have the correct pointy shape.

Bettas are full, and their colors shimmer from red to pink, from pink to yellow, from yellow to orange, from orange to green, taking all sorts of shades. Especially bright color can be observed in males, suiting the "cock" fight. It is curious to watch the fish and when they inflate their gills in the excited state, forming a protruding "collar" around his head.
