Betta Fish

Southeast Asia, specifically Cambodia, Laos, Myanmar, Malaysia, Indonesia, Thailand, and Vietnam, is home to the freshwater fish known as the Betta (Siamese fighting fish). Due to their widespread appeal as pets and their comparatively low maintenance requirements, Betta splendens are among the most widely kept aquarium fish in the world. There are 73 species in the genus Betta, but only one is given the name "betta". The Siamese fighting fish is not only well-known internationally, but it is also Thailand's national aquatic animal, which continues to be the country's principal source of betta breeding and export. The IUCN has classed Betta as "vulnerable" due to rising pollution and habitat destruction, despite the fact that they are often used as pets.

Typically, B. splendens reaches a length of 6–8 cm. Although B. splendens aquarium specimens are well recognized for their vivid colors and huge, flowing fins, wild fish only display vibrant colors when they are agitated; their usual coloring is often green, brown, and grey. Siamese fighting fish have been intentionally developed in captivity to exhibit a brilliant variety of colors and tail patterns.
