Temperature Water cools down at night.
Oxygen Levels Plants produce less oxygen in the dark.

These changes influence how Betta fish and other aquatic creatures behave and survive. Betta fish have adapted to these nighttime conditions in their natural habitat.

Scientific Insights Into Betta Sight

Betta fish are colorful and fascinating creatures. But can they see in the dark? To understand this, we need to explore the scientific details of their vision. This includes examining the anatomy of their retina and the roles of photoreceptor cells.

Anatomy Of Betta Fish Retina

The retina is a thin layer of tissue at the back of the eye. It is crucial for vision. In betta fish, the retina has two main types of cells: photoreceptors and ganglion cells.

The photoreceptors detect light and color. The ganglion cells send visual information to the brain. This process helps betta fish see their surroundings.

Photoreceptor Cells: Rods Vs Cones

Photoreceptor cells in the retina come in two types: rods and cones. Each type has a different function.

  • Rods: Rod cells are sensitive to light. They help betta fish see in low-light conditions. Rods do not detect colors. They only see shades of gray.
  • Cones: Cone cells detect color. They work best in bright light. Betta fish have more cones than rods. This means they see colors well during the day.

Betta fish have a unique balance of rods and cones. This allows them to see both in light and dim environments. But they see better in the light.

Understanding these cells helps explain how betta fish see. It reveals why their vision changes in different lighting.
