The Siamese fighting fish (Betta splendens), native to South-East Asia, is one of the most popular aquarium fish species purchased by tropical fish enthusiasts. Easy to keep, combined with its exotic, colourful appearance, this is an iconic species among novices which has undoubtedly inspired numerous enthusiasts.

Originally used as part of a subsistence economy, for its propensity to fight other males of its species (hence its common name), over time, it has attracted an increasingly larger audience.
