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.

BREEDING: Best bred with spawning mops allowing the fry to be raised seperately

Fishkeeping Facts and Tips

What fish are good community fish? There is no absolute answer to this, but in general a community tank should contain only species that will tolerate each others behaviour, are approximately the same size, eat the same foods, and accept the same water conditions. Hardy tank bred fish that have adapted somewhat to local water conditions, and have no special dietary requirements usually make good candidates
