Window screens are not designed for use in aquariums and can pose several dangers to your fish:
* Sharp edges: The mesh of a window screen can have sharp edges that can cut or injure your fish.
* Rust: The metal of a window screen can rust, contaminating the water and harming your fish.
* Blockage: The mesh can trap debris and food, creating a breeding ground for bacteria and hindering water flow.
* Stress: The presence of a screen can stress your fish, especially if they are trying to swim through it or are constantly bumping into it.
Alternatives to window screens:
* Dividers: There are specifically designed aquarium dividers available that are safe and effective for separating fish.
* Floating plants: Certain floating plants can provide natural barriers and create separate zones within your tank.
* Multiple tanks: If you have multiple betta fish, consider keeping them in separate tanks to avoid aggression.
It's important to prioritize the safety and well-being of your fish. Using a window screen as a divider can be harmful and is not recommended.
