The betta fish is a unique species, one that is enjoyed by fish lovers around the world. Because this fish is so well-loved, in this article we will explain the distinct symptoms and abilities bettas possess that make them similar and actually different than most fish today.
Unlike humans, bettas’ eyes are located on the sides of their head, which is known as monocular vision. While humans can only see straight in front of them, bettas have the ability to look in two separate directions at the same time! Unfortunately, this causes them to lack depth perception. In our eyes, the shape and curve of our eye lens is changing to achieve the right focus. However, in bettas’ eyes, the eye lens remains the same. Bettas find it difficult to adjust to brightness changes because of how slow their iris works, and as a result, they have relatively poor vision. To help this handicap, they have a “lateral line” which measures water pressure using its small holes which are connected to specialized nerve endings. This helps the betta to avoid obstacles in its way. The brain deduces those nerve signals as a picture of its environment so the betta can find food. This helps them compensate for their weaker eyesight.
Taste and Smell
Betta’s taste buds are on their lips, mouth and even his fins. Like humans, they inhale smells via the nostrils. Both senses help them because they react to chemicals in the water. Those chemicals let them know when there is food around, or if there is a predator nearby. However, bettas can only sense those chemicals within a short distance.
A Betta’s ear structure is pretty simple; it only consist of a single inner chamber. A Betta Fish hears by listening for vibrations in the water. These vibrations enter the sensory mechanism in the chamber to supply sound. The swim bladder also helps the betta’s inner ear by distinguishing and heightening sounds.
Bettas originated from swamps and rice patties which were poorly oxygenated. The labyrinth, which means “maze”, is a special repertory organ that is found in Anabantoidei. This organ is important because it allows oxygen to be taken in from the air directly into the bloodstream. This is a huge survival advantage when fish are in waters that contain poor oxygen. It is located below the gills, inside of the betta’s head. It contains rosette-shaped plates that have thousands of blood vessels within them.
The negative downside to bettas having this unique organ is many owners believe Betta fish can be kept safely in overcrowded conditions. What they fail to realize is that bettas add the same amount of waste to the tank as any other fish and can just as easily obtain a disease. Bettas should not ever be kept in small bowls for a long time. It is better for their overall health to be in larger aquariums or tanks, where they can swim freely in healthy water conditions.
