## Quick answer

The betta, or Siamese fighting fish (Betta splendens), is a small, brilliantly coloured freshwater fish originally from the shallow ponds, rice paddies, and slow streams of Southeast Asia. Domesticated for centuries, it is now one of the world's most popular aquarium fish, prized for flowing fins and vivid colours. Bettas grow to about 6–8 cm and usually live 2–4 years in home aquariums.

## Origins and domestication

Betta splendens has been kept and bred in Thailand for well over a century, first for the sport of fish fighting and later for its ornamental beauty. Selective breeding has transformed the plain, dull-brown wild fish into hundreds of colour and fin varieties, from crimson veiltails to iridescent blue halfmoons. The name "Siamese fighting fish" comes from the males' natural aggression toward one another. Today the domesticated betta is a global aquarium staple, quite different in appearance from its wild ancestors in Southeast Asia. While the pet betta is everywhere, the wild Betta splendens is listed as Vulnerable by the IUCN, as the shallow wetlands it depends on are lost to farming and development.

## Help protect the Betta Fish

Ocean wildlife is under mounting pressure from overfishing, bycatch and plastic pollution.
