No, Bettas actually have something called a labrinthiform organ behind their gills. This allows them to store some oxygen, and they tend to gulp air from the surface. If you are going to have a lid on the Betta's home, be sure to leave a small air gap between the waterline and the lid for them to gulp from.
No they breathe from the top of the water like a porpoise
Betta fish do not need to be in oxygenated water because they gulp air from the surface of the water. They can be kept in a variety of small containers. I found some really stylish ones online at www.bigalsonline.com. I attached a link for you!
Yes, but if he is nesting, it needs to be turned very low so as to avoid damaging his bubble nest.
There is a large number of different types of fish that have air sacs and can gulp air. These fish species are referred to as "labryinth". The by far most popular Labryinth fish is The betta Splendid or Betta fish.
Betta fish breathe air....yes... that's right... they breathe air. They breathe air because they have an organ by their gills that is called the Labyrinth's Organ which allows them to breathe air. They breathe air by coming up to the surface of the water. Then they gather air in their mouths and hold their breath underwater.
Fish that can breath air directly from the surface, such as the ever popular betta, are referred to as labyrinth.
All fish do it. If it just opens its mouth and lets out air it is just doing fish things.
Betta fish do not eat fish.
other Betta fish and the bigger fish.
No betta fish are carnivores.
Not in the same way that people 'burp' but they can and do 'gulp' air.
The cover is necessary for Bettas. It keeps the air above the water moist and warm so that when the Betta takes in a gulp of air it will not harm the fish.
