Multicolour/Rainbow platy fish display a range of iridescent colours across their bodies that sparkle under aquarium lights and contrast beautifully against their black tail and pale head. The rainbow platy is a perfect species for aquarists who want as many different colours in their tank as possible. The sparkling of the iridescent colours is exaggerated when these platies swim together.
