The Betta splendens, also known as the fighting fish, is native to Southeast Asia. Famous for its bright colours and spectacular fins, it is one of the most popular fish in aquarium keeping. It lives alone but is curious and interactive with its keeper.

• pH: 6.0-7.5
• GH: 4-10 °dGH

6. Breeding

The male builds a nest of bubbles on the surface to hold the eggs. Reproduction requires a stable temperature (27-28°C) and a separate tank. After laying, the male looks after the eggs until they hatch.
