* Overheating: Direct sunlight can quickly heat up the water in their tank, potentially leading to dangerous temperature fluctuations and even death.
* Algae Growth: Sunlight encourages the growth of algae in the tank, which can cloud the water, block light, and harm your fish.
* UV Damage: While betta fish can tolerate some indirect sunlight, prolonged exposure to UV rays can damage their skin and eyes.
What you should do:
* Indirect sunlight: If you want some sunlight, consider placing the tank in an area with filtered, indirect sunlight.
* Shade: The best option is to keep your betta fish tank in a shaded area that receives no direct sunlight.
* Appropriate lighting: Use a quality aquarium light designed for betta fish tanks to provide them with the necessary light for their well-being.
Remember, betta fish are sensitive creatures. Providing them with the right environment is crucial for their health and happiness.
