Description: An elongated, laterally compressed fish with a rounded caudal fin and an upturned mouth. The coloring is highly variable, although fins are not nearly as elongate as those of Betta splendens. The edge of the anal fin is fairly straight, and not flowing. Females have duller colors.
Males are more colorful and have more elaborate fins.
Use a shallow spawning tank with no water current, plants, and retreats for females. The male constructs a bubble nest at the water's surface. After each pairing, the male pushes and spits the eggs up to the bubble nest. In all, 400-500 eggs are laid. Remove the female after spawning. The male cares for the eggs and should be removed after 24-36 hours, when the eggs hatch. The fry look like little hairs at the water's surface. Start feeding with micro foods and egg yolk. Later the fry can be fed with powdered dry foods.
