The story is about The Rainbow Fish, a fish with shiny, multi-coloured scales. He has blue, green, purple, and pink scales. Interspersed with these colorful scales are shiny, holographic scales which are his favorites. The other fish from his gang also have scales, but only scales matching to their real colors. However, they wish that they had shiny silver scales like the Rainbow Fish. One day, a small blue fish (wishing he could have shiny silver scales) asks the Rainbow Fish if he could have one of his shiny silver scales. The Rainbow Fish refuses in a very rude manner. The small blue fish tells all the other fish that The Rainbow Fish was being rude, and as a result, the other fish do not want to play with him any more.
