Description: The Rummy Nose Rasbora is a streamlined fish. The coloration completely differs between the sexes. The males have a “nose” and tail tips which are orange-red, and their body tends toward a rather milky blue color. The females are silver with transparent fins. Especially small scales give both sexes their even looking coloration.

The Rummy Nose Rasbora is an omnivore and requires a healthy balance of foods. Since specimens are largely still from the wild or are a few generations past it, some aquarists find it difficult to get them to accept prepared foods. However, prepared foods are really the only practical way to provide balanced nutrition, so fish should be weaned off of an exclusive diet of live foods.
Because of their sensitivity to water conditions, they are generally not a good beginner fish. Otherwise they are hardy and easy enough to care for. Some plantings of hardy broad leaved rosette plants, like Anubias or Sword Plants make them feel at home. Since they are so small, a school can be housed in as small an aquarium as five gallons, however, that little water is difficult to maintain. A larger tank, 10 or 20 gallons, will allow these fish to comfortably school and swim back and forth. These fish do best kept in groups of at least six or more. The tank should be carefully covered as these fish are liable to jump if startled or excited.

The males have a red “nose”, red tips on their fins, and are milky and light blue. Females are usually smaller, and are glassier and silver in coloration.

A consensus has yet to be reached on the most reliable home breeding process. What is known is that water conditions must be exactly within the above parameters. Females seem to be only willing to breed at certain times. Some suggest that a period of cool temperatures in February helps. Temperatures in their native lake dip down to about 57 - 64° F (15 - 18°C) around that time, so this seems to encourage spawning. These fish have been reported to leave eggs on leaf undersides and in spawning mops. Also, eggs and fry should be protected from their parents and other fish.
