Before you buy
What to consider
When selecting a betta tank, start with water capacity. A minimum of 5 gallons provides a stable environment, but smaller bowls can work if they include proper filtration and regular water changes. Next, consider filtration type; bettas prefer gentle flow, so sponge or low‑output power filters are ideal. Lighting is another factor - LED lights that offer a natural spectrum support the fish’s colors and any live plants you may add.
What to consider
Finally, think about maintenance and space. Acrylic tanks are lighter and easier to move, while glass offers scratch resistance. Look for models with removable lids or front panels for quick cleaning, and check whether a heater or thermometer is included if you live in a cooler region. Balancing these criteria with your budget will help you choose a tank that keeps your betta healthy and vibrant for years to come.
Quick answers
A minimum of 5 gallons is recommended to provide stable water parameters and room for swimming.
If the room temperature stays above 75°F, a heater is not required; otherwise a small 50‑watt heater works well.
