Can Betta fish see in the dark?


Updated on:

Betta fish, also known as Siamese fighting fish, are native to the shallow waters of Thailand, Cambodia, and Vietnam. They are known for their vibrant colors and long, flowing fins, making them a popular choice for aquarium enthusiasts. But can Betta fish see in the dark?

Betta fish have excellent eyesight and are able to see in low light conditions. They have large, protruding eyes that are positioned on the sides of their head, giving them a wide field of vision. Their eyes are also adapted to see through the murky waters of their natural habitat.

Betta fish have a special layer of tissue behind their retina called the tapetum lucidum, which reflects light back through the retina, increasing their sensitivity to low light. This adaptation allows them to see in dimly lit environments and navigate through their surroundings even in the absence of light.

However, it is important to note that Betta fish still require a certain amount of light to function properly. Without adequate lighting, they may become disoriented and experience difficulty finding food or avoiding obstacles in their environment. It is recommended to provide a consistent light source for Betta fish, such as a low-wattage aquarium light, to ensure their well-being.

In conclusion, Betta fish have remarkable vision and are able to see in low light conditions thanks to their unique eye structure and the tapetum lucidum. While they may not require bright lighting, they still need some level of light to thrive and maintain their health.
