Tanks for housing just your Siamese fighting fish should be at least 10 litres in volume, with an optimal size of 20 litres or greater.

Siamese fighting fish require a pH of around 7.0, GH 7-9º, KH 5-8º.

Siamese fighting fish require warm temperatures of around 24-28°C, with minimal fluctuations.

Adequate filtration should be installed, but avoid filters that cause excessive surface-water movement as Bettas are surface-breathing fish from slow-moving waters, and cultivated forms can be weak swimmers.

Males and females are not recommended to be housed together, unless it is for breeding purposes.
