Siamese Fighting Fish


(Betta splendens), a fish of the family Anabantidae of the suborder Anabantoidea (labyrinthic fishes). The fish is up to 8 cm long. The males, especially during the mating season, are brightly colored. Siamese fighting fish are found in the fresh waters of Southeast Asia (India, Thailand, and the Malay Peninsula). The male builds a nest out of air bubbles (foam) on the surface of the water; the female deposits the eggs on the bottom of the body of water, and then the male carries them in his mouth into the nest, where he guards them and subsequently the fry. The Siamese fighting fish easily reproduces in small aquariums (at temperatures of 25° to 30° C). Veiled and variegated forms of the fish are bred in aquariums; these forms include the red, cornflower blue, rose, blue, and green fish.

In neural terms, the aggressive display of the Betta splendens was studied with ablation techniques and discrete lesions of the telencephalon (Marino-Neto & Sabbatini, 1983a, 1983b) and through the waterborne presentation of neurotransmitters (Baenninger, 1968).
