Description: This fish was named in honour of it's discoverers, Barbara and Allan Brown. In both sexes the body is deep wine red with bluish-green midlateral blotch, which varies in size according to collection locality. This blotch is slightly less pronounced in females. The dorsal fin has 10-11 rays, the leading pelvic fin rays are white, and the iris is iridescent blue. Good health requires strongly acidic water, also needed for maintaining the stickiness of the bubblenest. Males are more colorful and develop longer fins than females as they mature.

Their breeding is hard, as they need very soft and acidic water. At spawning the male builds bubblenest which may be incomplete, but enlarged afterward. Plastic tubing are often used by breeders to offer potential nesting sites. Just prior to spawning the body color of the female pales and dark bars appear on the flanks. They spawn below the bubblenest and when the male embrace the female with its body, the female releases the eggs and the male fertilizes and transfers them to the nest. The number of the eggs are usually between 20 and 50. Eggs hatch in 36 hours, and the fry are free-swimming and start feeding at 3-4 days later. In response to disturbances, the male may take the eggs or larvae into his mouth and move them to another location where he builds another nest. Sometimes he holds them for protracted periods, leading some to suggest that at least one stock may be bouthbrooders. The female defends the territory and the male guards the nest. Larger fry do not feed on younger siblings, and a family of mixed ages and sizes may defend a territory. Maturity is reached in 6 months, maximum size is reached in a year.
