AQUARIUM CARE: The threadfin rainbow is a very attractive, but very delicate species. It comes from the slower moving waters of New Guinea, so stronger currents should be avoided. This species likes a well-plated tank with floating plants.

It is not difficult to keep, but really should go in a species tank, or a community of the most delicate fish.
