Since rainbowfish are known to eat their own eggs, it is safest to move the eggs to a separate fry rearing container. A 2-litre plastic container from the kitchen is large enough to work as fry aquarium for 25 fry while the fry are still young. Use water from the breeding aquarium to fill them, that why the eggs does not have to adapt to new conditions. Make sure that the temperature is kept up in the fry aquarium. One way of achieving this is to let the containers float in another aquarium or in a tub where you have placed an aquarium heater or two. The temperature should be kept in the 25-28 degrees C (77-83 degrees F) range.

Red Rainbowfish do fine in a community aquarium of similarly sized fish, but do exceptionally well in a geographical tank stocked with other rainbowfish. Although generally non-aggressive, overly aggressive or very shy tank mates will make bullies out of them. Mix them with other playful but good natured fish for best results. If in a tank with both other males and females, the males will occupy themselves by displaying their brightest and best red colors and flaring their fins. When males are displaying, you may notice some chasing between rainbowfish, but this is rarely a concern unless a fish is injured, has nowhere to hide, or is constantly harassed (usually a result of one of the first two).

If you have a 40 litre (roughly 10 gallon) aquarium, you can keep up to 15 rainbowfishes if you choose small species such as Pygmy Rainbowfish (Melanotaenia pygmaea) or Dwarf Rainbowfish (Melanotaenia praecox). An 80 litre (roughly 20 gallon) aquarium can house an even larger group of small species, or up to 15 medium sized rainbowfishes like Boeseman's rainbowfish (Melanotaenia boesemani) or Duboulay's Rainbowfish (Melanotaenia duboulayi). A 150 litre (roughly 40 gallon) aquarium is large enough for up to 15 large rainbow fishes, e.g. Red rainbowfish (Glossolepis incisus) or Sepik Rainbowfish (Glossolepis multisquamatus). The recommended water conditions will depend on which species of rainbowfish you keep and obtaining species specific information is therefore always recommended. Some species are used to soft and acidic waters, while others need alkaline conditions to thrive in the aquarium. Fortunately, a lot of rainbow fishes are quite adaptable when it comes to water chemistry and many species can be kept in aquariums where the pH-value is 6.5-7.5 and the hardness between 0 and 100 ppm. Create a lot of hiding spots for your fish, since this will make them fell less stressed and more secure in the aquarium. Live plants are recommended for the rainbowfish aquarium since it makes the fish feel at home and brings out their true colours. Plants like java moss are also appreciated spawning sites for rainbowfish. If you haven’t kept live plants before, ideally go for sturdy species like java fern and java moss. These species can adapt to most water conditions and does not require any special lighting or extra carbon dioxide. In most cases, the waste produced by your fish will be sufficient as fertilizer. One of the reasons behind the scarcity of Rainbowfish within the hobby is probably the fact that young Rainbowfish look quite dull. Fish stores usually sell small Rainbowfish that have yet not developed their true colours. If you buy young Rainbowfish and take good care of them, they will mature and develop their adult colouration.

It is unfortunately quite common for fish stores to place their fish in aquariums that are too small or too crowded; conditions that can easily make even an adult Rainbowfish look pallid and unappealing. Barren aquariums without suitable hiding spots, or aquariums with aggressive species, can also make the Rainbowfish dampen its colours, since it will feel highly stressed.

All the various Rainbowfish species are quite similar when it comes to feeding requirements, desired water chemistry, temperature, breeding habits etcetera. There are however minor differences between the many species so it is always a good idea to research your particular species before you bring them home. Generally speaking, the horizontal length of the aquarium is much more important than the depth, since Rainbowfish spend most of their time near the surface and rarely venture any deeper down. As mentioned above, the size varies considerably between the different species and it is therefore impossible to recommend an aquarium size.

Keepers of Rainbowfish usually opt for a dark substrate in the aquarium and strong lighting since this make the Rainbowfish look more vibrant. The natural Rainbowfish habitat is filled with aquatic plants and rainbows will therefore appreciate a planted aquarium. There should also be some open space available for these active and energetic fishes to swim around in. Keep the aquarium closed to prevent the fish from jumping out of the water.
