A mainstay of the hobby the neon is colorful peaceful and readily available.
Not one of the easiest fish to keep they do best in an established aquarium.
Their bright colors and peaceful nature still make them one of the most
sought after fish.

Western Brazil, Northern Peru and Colombia. Found in the Iquitos and
Amazon rivers and some of their tributaries.
General Body Form
A slender fish somewhat spindle shaped with little lateral compression.
The nose is blunt and the belly area seems to be rounded in the females
and concave in the males. They can reach a length of about one and one
half inches (4cm)
Starting at about the center of the body, there is a wide bright Red
band extending to the start of the Caudal fin. Above this is a Blue
band with a green sheen that runs from the upper part of the eye to
the Adipose fin. The upper-side is Olive Green and the underside is
Silver in color. The Anal fin is milky white to transparent. The striking
contrast or the Red and Blue makes the Neon one of the most colorful
and popular of the fish we keep.
Neons are happiest and show off their colors best in a tank with subdued
lighting and a dark substrate. The water should have a pH of 7.0 and
the temperature maintained between 68° and 79°f, hardness to 20°. The
tank can be small and decorated with live plants and some driftwood.
Stock the aquarium with equally peaceful species and keep them in as
large a school as possible. Neons are now bred in large numbers and
are able to tolerate a wide range of aquarium conditions, however this
mass scale breeding has weakened their natural robust-fullness and losses
are usually high when first bought. Once established they are easily
fed and cared for with flake and frozen food.
Egg scatterer, requires soft, very clean water. Failures in breeding
are in most cases due to unsuitable water conditions. To spawn them,
you will need a small tank placed in a dark spot as the eggs seem to
be light sensitive, a 2 inch layer of half inch rock and some bunches
of fine textured live plants like Myriophyllium are suitable as the
spawning medium. Only young fish should be used for breeding and at
least 5 fish (with a ratio of 2-1 males) that have been separated (put
the females in the tank that will be used for spawning) for 2 days and
fed some live foods. The temperature should not rise above 75°(21 to
23°C) Keep a lid on this container as they will jump out. Keep the breeders
together for 24 hours and then remove them. They usually spawn early
in the morning. The clear eggs are laid among the plants and barely
stick to them. In 22 to 26 hours the eggs hatch and the fry are very
hard to spot, but appear 3-4 days later at which time they are free
swimming and will need to be fed infusoria. The species is not very
prolific and A good spawn would be 40-50 fry
