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 senses 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 consists of a sole 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.

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 shouldn’t ever be kept in small bowls for a long time. It is better for their overall health to be in bigger aquariums or tanks, where they can swim freely in healthy water conditions.

Betta fish as a pet

The betta fish is known for its incredible beauty and its warrior-like personality. Betta fish are among the second most popular home aquarium pets after the goldfish. This is due to the wide variety of conspicuous and stunning betta colors and shapes to choose from. This is the ultimate reason why many aquarists are betta fans.

Factors to consider when picking your Betta:


You will notice that dark colors (blue and red) are the most common, but you can find some very unique colors also!

Caught your eye? This may be your new pet


Bettas can be very social with their owners. Check their rate of receptiveness and make up the best decision.


A bright fish may not be any healthier than a dull one. What you do want to notice is if it’s shiny. This is a sign of good health.

Making your Betta’s home

It is important to have your Bettas home ready before you bring home your new friend. The less time you have it outside its tank the better

Betta fish survives best in fresh water environment.

Bettas can be housed with other species of fish under certain circumstances:

  • No nibblers
  • Avoid bigger and colorful fish since they makes them feel intimidated
  • Many bottom feeders can live with bettas

Be very cautious when dealing with male bettas. Never put them together whatsoever. This is because they tend to be so aggressive such that they even attack their own position when there tend to be threats or danger signs. They fight to appoint of killing themselves. However, female bettas can be kept together. This is not an implication that they are harmless. They are less aggressive and rarely do they kill each other. Bettas love to have their own territories and if some other fish tries to dominate them, they never hesitate to attack and fight aggressively. This happens even in the natural environment where bettas fight for their privacy and territory in river basins.
