Betta palangkaraya officially described
It seems that B. palangkaraya/sengalang has now officially been named and described as B. hendra, a member of the coccina complex group.
Betta hendra is named for its discoverer Hendra Tommy and has also been traded as B. sp. ‘Sebangua’ in the past. Its colour pattern looks similar to that possessed by members of the B. foerschi group of species but its breeding strategy, adult size and behaviour mean its actually included in the B. coccina group.
Hailing from Melbourne, Australia, I currently keep and breed a number of species from the coccina complex.
