AQUARIUM CARE: A relatively widespread rainbowfish with a number of truly beautiful poulations. This really is a jewel rainbowfish! It is a fine community species in larger tanks (at least 48"), and appreciates flowing water.

A suitable tankmate for similarly sized rainbowfish, tetras, cyprinids, and even Lake Tanganyika cichlids.

BREEDING: Best accomplished with spawning mops and the fry raised seperately. Fry can immediately take newly hatched artemia nauplii

Fishkeeping Facts and Tips

A shoal of tetras? A well-planted Amazon tank with a large shoal of neon tetras looks amazing. The bright neon blue and red against a green leafy background has got to be one of the best combinations in fishkeeping. It is no wonder that these are one of the most popular aquarium species. But as with all shoaling species, tetras need to be kept in a group to be happy. The larger the better (without overstocking your tank). Six individuals is usually seen as the absolute minimum in a shoal, but more is better. The effect of a large tank with a shoal of 30-40 neon or cardinal tetras is simply stunning
