The Pi Betta is named after the Greek letter π (pi), due to the shape of the dark marking on its throat. It can be found in Malaysia and Thailand. It is primarily found in well shaded peat forest blackwater swamps and creeks.

Depending on the fish itself, they can be kept with other peaceful tropical fish. Betta fish are a labyrinth fish, meaning they have evolved over time to have an addition organ that allows them to breath surface air. 

A golden rule of keeping bettas : Don't put two bettas in the same fish tank unless you are ready for a fish fight.

Betta Fish Tank Setup:

Aquarium Filtration for Betta Fish

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. 

Aquarium Heaters for Betta Fish

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.
