A single male betta fish can sometimes be kept in a large community aquarium without any other bettas, but they should be monitored closely. If your betta shows any signs of aggression towards the other fish, remove the betta from the aquarium.


 Bettas need an aquarium with at least 3 gallons (11 litres), a filter and a heater.

The aquarium should be near a power source, away from direct sunlight.

Water weighs about 8 pounds per gallon. Pick a very sturdy, stable base for your aquarium. There are special stands designed to support aquariums.




Your fish will produce ammonia all the time, but it’s toxic in any amount. Even with water changes, and cleaning, there will always be ammonia in the water. The only way to make ammonia go away, is growing good bacteria in the filter. This will keep the water safe and ammonia free. 

You also need to make sure your fish’s tank stays at the right temperature. Betta fish water temperature should be around
77-82°F (23-27°C). Choose an aquarium heater with 5 watts of power for each gallon of water in the tank.

Make sure to use dechlorinated water!  Seachem Prime is the best water conditioner choice.


Light isn’t the most important detail when it comes to caring for your betta fish, but you should mimic day and night cycles the best you can. It is not recommended to leave your Betta’s tank in direct sunlight, because that can cause algae to grow.


Layer 1-2 inches (3-5 cm) of gravel or sand on the bottom of the tank. This equals about 1 pound of gravel per gallon of water. Rinse the gravel before putting it in the aquarium; never use soap.



Decorate your betta fish aquarium with live or  artificial plants, ornaments and more to add some personality to their environment. Ensure your fish tank decor is not sharp, as it risks shredding the fins.
