Betta
Betta splendens
Animalia›Chordata›Perciformes›Osphronemidae
📍 Southeast Asia
The Siamese fighting fish is celebrated for its spectacular finnage and bold colours. Males are highly territorial and must be kept singly or with carefully chosen, non-nippy tankmates. They breathe atmospheric air via a labyrinth organ, so surface access is essential.
