How to Choose
Size matters
Many experts recommend 5 gallons or more for a single betta. Small tanks swing in temperature and water quality faster.
Heat and filtration
Bettas need steady warmth around 78 degrees and gentle filtration. Check whether the tank has room for a small heater and a low-flow filter.
Lid and ventilation
Bettas breathe air at the surface and can jump, so a lid with room for air is helpful.
Hiding spots and plants
Soft plants and caves reduce stress. Avoid sharp decorations that tear fins.
Shape and stability
Wide-bottom tanks give more surface area than tall narrow ones and are easier to keep stable.
Common Mistakes to Avoid
- Keeping a betta in a tiny unheated bowl
- Using a filter with strong current
- Skipping water testing
- Putting two male bettas together
Setup and Care Tips
- Add a small adjustable heater
- Use live or silk plants
- Do small weekly water changes
- Feed small portions once or twice a day
