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.
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

They may be vicious to plants.
