Betta Pugnax
The Pugnax Betta fish is larger and has a thicker body than the more common Betta splendens. They are distinguished by their elongated ventral fins and by the iridescent blue in their heads and in the area around their gills. Both sexes have the spiked tail which is an extension of the long middle rays in the caudal. When the fish spawn, the male holds the eggs in his mouth and throat for over a week until the eggs hatch, during which time the male's girlfriend guards him to ensure nothing disturbs his peace.
The Pugnax was first identified for classification around 1850 and is commonly called the Penang Mouthbrooding Fighter. The Family is the Belontiidae and its origin is Cambodia, Malaysia and Indonesia. The pugnax will grow to about four inches. Carnivorous by nature, in controlled aquatic environments it will eat flake and frozen foods. The temperature range is from 72-82°F with a pH of between 6.0 to 7.0. The betta pugnax can be kept in community tanks in softwater. Clean, clear water with plants for cover as the males will take shelter as they incubate the eggs. The fry are to be fed brine shrimp or a similar first food.
The Pugnax Bettas are also called Mouthbrooding Betta, Malayan Betta
Penang Betta, Giant Betta and Big Eye Mouthbrooder
