Visarute Angkatavanich, a photographer based in Bangkok, Thailand, makes these beautiful captures of Siamese fighting fish (often commonly called bettas). These fish are native to Thailand, Laos, Vietnam and Cambodia, although wild Siamese fighting fish aren't brightly colored like the ones bred to be aquarium pets. In the wild, they can be found in canals and other freshwater pools.
Angkatavanich skillfully captures the grace, allure and temperament of the agressive bettas, with their fins and tails flowing as they appear to confront the viewer, unafraid. As someone who kept bettas as well as large aquariums of freshwater fish (including close relatives of the Siamese fighting fish, gouramis), for about ten years, I think these are fantastic representations of the species.
Limited edition prints of Angkatavanich's work are available through La Lanta Fine Art. -Via Colossal.
