Betta Fish Tank Setup: The Honest Beginner Guide
A complete, no-nonsense walkthrough: tank size, filtration, heating, planting, and the mistakes that actually kill bettas. We tested five starter kits across three months to find what works.
- Minimum tank size: 5 gallons (not 1)
- Filter flow: why gentle matters
- Heater placement and temperature stability
- Plant selection for low-light betta tanks
Our Signature POV
Botanicals & Blackwater
Tannins from catappa leaves and alder cones soften water and support betta health. Our dosing guides show exactly how to build a safe blackwater tank without crashing parameters. This is what sets TanninLab apart.
