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...
