The ideal sized tank for a betta fish is 15L or larger. However, you could also go with a nano tank as small as 5L. In nature these fish inhabit very weedy habitats and are perfectly adapted to living in small spaces as long as water quality is kept high.

Betta fish are naturally found in still or slow moving waters. Due to their large fins, they can be pushed around in strong currents. We recommend gentle water flow and filtration. Sponge filters, under gravel filters, and hang on filters are great options if keeping in smaller aquariums.
We use a heater mat for the smaller tanks and bowls. Or for larger aquariums you will need an aquarium heater and a thermometer to monitor temperature. They prefer warm tropical waters and generally require a heater in the winter months in most areas of Australia.

Showcase your betta fish with artificial lighting. A small light above the aquarium that runs during daylight hours will replicate the natural environment. Dimmable lighting options are available which will help manage algae in the aquarium.

Live plants are a great idea. Betta fish love lounging on the leaves and hiding in them to sleep. Live plants will also uptake some nitrates in the aquarium, helping remove nitrates and prevent algae.

Betta fish do not have particular substrate requirements. Aquarium sand, gravel and pebbles are all good options.
