How many gallons do betta fish need?

Betta fish, while small, are surprisingly active and curious. While you can technically keep them in small bowls, it's not ideal for their health and well-being. A minimum of 2.5 gallons is recommended for a single betta.

Here's why:

* Water quality: Smaller tanks are more prone to rapid fluctuations in water parameters like ammonia and nitrates, which can be harmful to bettas.

* Space: Bettas are known for their elaborate fin displays and enjoy swimming around. A larger tank allows them more room to move and explore.

* Enrichment: With more space, you can provide enrichment items like live plants, caves, and ornaments to keep them stimulated and entertained.

Here's a breakdown of recommended tank sizes:

* Single Betta: 2.5 gallons minimum, 5 gallons ideal

* Betta with tank mates (small, peaceful fish): 10 gallons or larger

Remember: It's always better to err on the side of a larger tank.
