In practice, however, you don’t need very soft, acidic water to keep neons and cardinals healthy. Simply mixing your hard tap water with pure water (deionized water, reverse-osmosis water or rainwater) in a 50:50 ratio will create stable, not-too-hard water conditions that your fish will thrive in.

Dwarf Neon Rainbow (Melanotaenia praecox) - one of the few Rainbows I really like (their body shape bugs me). They are great little fish though and what they lacked in "beautiful body shape" (to me) they made up with personality and subtle color! Dwarf Neon Rainbowfish

The Dwarf Neon Rainbow originates from New Guinea. It is also known as the Dwarf Rainbow, the Neon Dwarf Rainbow and the Neon Blue Rainbow. It is probably the most popular of all rainbows, because of its small size, its bright color, its active schooling nature and its compatibility with many other fish. The body is bright iridescent neon blue and silver. Males have red on the edges of their dorsal, anal and caudal fins. Females tend to be paler and to have yellow on their fin edges. Dwarf Neon Rainbows should be kept in groups of at least 6. They like well planted tanks with lots of open swimming space. They will eat floating flake foods and freeze dried bloodworms. They will also benefit from occasional live brine shrimp feedings. Size Appeal: Since most Americans start their fish keeping careers with a 10-gallon tank, small fish work best for them. Not the cheapest fish in the barrel (like neons, moons, or danios), they're a definite step up at a still reasonable price. Dwarf neon rainbowfish also start developing their color potential at a much smaller size than most rainbowfish. They're still somewhat harder to find than the usual run of the mill community fish.Rainbow Fish for sale Premium Neon Rainbow Pictures: above: a 1.5" Neon Rainbowfish just like the ones we ship, below: a 2" Neon Rainbowfish that we raised up here with lots of tender lovin' care and lots of premium fish food.

They like all types of flakes. And, of course, love live and frozen foods. Remember that food that falls to the bottom will not be eaten. Add some scavengers or snails. Rainbowfish do not like dirty water. Temperature: Like most community fish, dwarf neon rainbowfish fare fine at 75 degrees Fahrenheit. They do okay slightly cooler and like to spawn when you bump them to 80F. Breeding: Most schooling egglayers breed best if you separate the sexes and condition them for spawning. Dwarf neon rainbowfish lay smaller quantities of eggs on more of a continuous basis. You needn't isolate the sexes for maximum production. You will need a scavenger-free aquarium though. Reputedly, the parents will not eat their eggs or fry. However, I would not trust the reputation of any parental units that eat as heartily as rainbows. Try the standard danio layer of marbles on the bottom to protect their eggs, or just assume you'll have plenty of eggs even if they do eat some. Some fish keepers house their breeders in net cages that allow the eggs to fall thru. They then periodically siphon the eggs out. Bare tanks work best for this process.
