What water temperature do betta fish need?

Betta fish thrive at 24–28°C. Use a heater to keep the temperature stable, especially in air-conditioned rooms or during Indian winters.

How often should I change aquarium water?

Change 25% of the water weekly for most freshwater setups. During monsoon season, reduce to 15–20% changes and always use a water conditioner to remove chlorine.

What is the minimum tank size for a betta fish?

The minimum recommended tank size for a single betta fish is 5 litres, with 10–20 litres being ideal. Larger tanks maintain more stable water parameters and are easier to manage.

Do aquarium plants need CO2 injection?

Most beginner-friendly aquarium plants like Java Fern, Anubias, and Java Moss do not need CO2 injection. They grow well under basic LED lighting and are excellent for low-maintenance planted tanks.

How do I cycle a new aquarium?

Run the filter for 7–14 days before adding fish, adding a small pinch of fish food daily to produce ammonia. This establishes beneficial bacteria that convert toxic ammonia into harmless nitrate. Test the water before adding fish — ammonia and nitrite should both read 0 ppm.

5 tips

Bettas need a minimum of 5 litres — bigger is always better. For community fish like neon tetras, aim for 40 litres or more. Rimless glass tanks look cleaner and are easier to maintain.
