Rainbow Fish Information: Care, Types and Breeding


Bright beautiful and full of life, rainbow fish are ideal inhabitants for your tropical aquarium. They're hardy by nature, comparatively resistant to disease, and peaceful in temperament. You couldn't find a better kind of fish to begin with.

So named for their bright, changeable colours, rainbow fish may puzzle you if you buy them when they're young, as they're very plain looking then. Bright colours develop in response to changes in social status, and with the onset of sexual maturity. They are at their most vivid during spawning. Rainbow fish are happiest living in shoals of at least six, and this will bring out their colours.



Although they will occasionally chase fish of other species, they have hardly ever been known to bite them, and they are generally peaceful fish who will get on with all kinds of other aquarium inhabitants. They're fast enough to be able to look after themselves in the presence of more aggressive fish, but do better if provided with plenty of hiding places, especially thickets of plants. Because of their speed you should make sure that they have plenty of open space to swim about.

The ideal diets of rainbow fish vary by species, but they can all do well on a basic diet of flakes and freeze dried food, with occasional meals of live brine shrimp or bloodworm. They may sometimes come into conflict with barbs and danios when competing for food.

Most rainbow fish need neutral water and are fairly hardy when it comes to water quality, though sudden changes will distress them. The trick to keeping them successfully is to change about fifteen percent of the water in your aquarium two to three times per week.


Types of Rainbow Fish

There are numerous species of rainbow fish to choose from. Fortunately, most will happily shoal together provided that you have at least one male and one female of each kind, so you can keep two or three species in your community tank.
  • Red Rainbow Fish -The males of this species will develop a beautiful rich ruby colour in the presence of females and if they have a dark coloured substrate. They may be vicious to plants.
  • Banded Rainbow Fish -With several colour variations, these striking looking fish are omnivores and benefit from a highly varied diet. They are among the most popular aquarium fish in the world.
  • Celebes Rainbow Fish -With a slender, elongated shape unlike that of their kin, these fish need very clean water and prefer subdued lighting.
  • Bosemani Rainbow Fish -These unusually shaped fish, half grey and half yellow, need a lot of space and are among the more difficult to keep.
  • Dwarf Rainbow Fish -Also known as blue neon rainbow fish, these tiny fish prefer well planted aquariums with slightly acidic water.
  • Herbert Axelrod's Rainbow Fish -These attractive, personable little fish need a diet containing plenty of vegetable matter.
