Also known as the Forest Betta, the Penang Betta has a large natural range. These fish tend to live in shallow streams in Asia, Malaysia and Singapore where the substrate is sandy and there is limited vegetation. The Penang Betta is one of the larger species of Betta, though females tend to be smaller than males of the species. This species is relatively devoid of coloration, having a silver to light brown body ornamented by a pale stripe through the eye.
