Getting the tank right is the single most important thing you can do for your Betta. Here is our honest advice:
Tank Size
All Betta tanks must be heated. Bettas are tropical fish from South East Asia and require a stable temperature of around 24–28°C. This is non-negotiable.
For a standard big-tailed Male Betta (Halfmoon, Crowntail, Veiltail etc.), we consider 25–30 litres the minimum. At this size, the only suitable tankmates would be some small cleaning fish or occasionally shrimp. If you want to keep your Betta with other fish, we recommend 40 litres or more.
Plakat Bettas are different. These are active, fast-moving fish that need more swimming space than their long-finned cousins. We would not recommend going below 50–60 litres for a Plakat, and they will do well in tanks up to 100 litres. A Plakat in a tank that is too small will show it — they can become stressed and restless without enough room to move.
Our view on Betta bowls and vases: We do not recommend them. Full stop. Bettas deserve a properly heated, filtered, adequately sized tank — not a decorative vessel. If you want to give your Betta the best life possible, a proper aquarium is the only way to do it.
We stock a wide range of tanks from 30 litres upwards, at a variety of price points and sizes, so there really is something for every budget and every space. Browse our aquarium range →
Plants and Decoration
Our preference is always real plants and natural decoration. A planted tank not only looks more beautiful — it provides genuine benefits for water quality and gives your Betta places to explore, rest and feel secure.
That said, we do stock a range of Betta-safe artificial plants and decorations — carefully selected to ensure nothing has sharp edges or rough surfaces that could damage delicate fins. If you are not yet ready for live plants, our artificial range is a safe and attractive option.
One thing to watch: avoid any decoration with sharp points or rough textures. Betta fins tear easily and a damaged fin is both stressful for the fish and a potential site for infection.
