Betta fish require water that is dechlorinated with a pH between 6.5 and 7.5, and a temperature maintained between 76 and 81 degrees Fahrenheit. Tap water is ideal for bettas if treated with a water conditioner to remove harmful chemicals like chlorine, chloramine, and heavy metals. Distilled water is not recommended unless minerals are added because it lacks essential nutrients for bettas.
Ideal Water Parameters for Betta Fish
- pH: 6.5 to 7.5
- Temperature: 76 to 81°F (24 to 27°C)
- Ammonia and Nitrite: 0 ppm
- Nitrate: less than 20-40 ppm
- General Hardness (GH): moderate, around 50 to 150 ppm
Types of Water
- Tap Water : Most accessible and suitable when treated with a water conditioner that removes chlorine and heavy metals.
- Distilled or Reverse Osmosis Water : Not recommended unless remineralized, as it lacks essential nutrients.
- Bottled Spring Water : Can be used if it meets suitable pH and hardness requirements.
- Well Water : May be used if tested and treated appropriately for pesticides, heavy metals, and hardness.
Additional Care Notes
- Using a heater to maintain temperature in the recommended range improves betta health.
- Regular water changes (about 50% weekly) help maintain water quality.
- Testing the water parameters before introducing the betta is recommended for best results.
This setup helps replicate the natural habitat conditions of bettas, promoting their health and longevity.
