hope your tank has some "flow" to it
Occurs in small fast flowing forest streams. Inhabits overhanging bank vegetation, submerged leaf litter and exposed roots of bank vegetation.
Reproduction: Mouthbrooder. Spawns in a depression on the substrate. Male broods the eggs in his mouth until hatching. Produces a minimum of 100 eggs.
General notes: "[Writing about the synonym Betta brederi Myers, 1935] A length of six inches is not uncommon. The color is typical too: dark green spangles over brown…The female frequently shows a strong striped pattern (horizontal), especially at spawning time…the dorsal fin tends to be pointed in both sexes, but that of the male has been described as "spear-like" and may be used as a sexing distinction. The male's anal fin is more pointed…with extended fin rays at the point. His tail too, comes more to a point than the female's…He may brood up to 40 eggs, and that is a mouthful…The eggs supposedly hatch in about three days. Then, he broods the fry in his mouth for another 14 days."
"Betta pugnax is another mouthbrooder. Dr. William Innes in Exotic Aquarium Fishes, calls b. brederi a form of [B.] pugnax, but here is the description from Sterba, 'Sober gray-blue to fine red-brown…Fins yellowish with rows of brown spots…occasionally very attractively colored…strikingly contrasted red-brown colour over the underside of the head and the belly…fins bright red.'"
