Betta fish, also known as Siamese fighting fish, are popular with aquarium enthusiasts due to their vibrant colors and long, flowing fins. But have you ever wondered how far can betta fish see? It turns out that betta fish have excellent eyesight and can see up to a distance of about 3 feet.

Betta fish have large, protruding eyes that allow them to see in almost all directions. They can see more colors than humans, including ultraviolet light, which enables them to detect prey and predators more easily. Their eyes are also sensitive to movement and can pick up on even the smallest motions, making them great hunters.

So placing their food slightly to the side of their face is important.

Can Betta See Depth?

Betta fish may have excellent eyesight, but do they also have the ability to perceive depth? This is an important factor in determining the distance a betta can see.

The eye of a betta contains 470 light-sensitive units (rods), which are placed in several rows, many more than most alligators or cats(maybe trillions?). But not enough rods to detect motion as clearly as humans, with over half a million.

All those 470 rods are spread out across the eye, though. How do you take this info from your brain(visual cortex), transfer it through nerves into the lateral line(special sensory receptor), and tell them something?
