Super-swimmer
The red rainbowfish lives in fast-flowing rivers. With its narrow body, it can easily swim against the current. It is an extremely strong swimmer and can actually swim vertically up a waterfall.
Colourful male
The male red rainbowfish is a bright red colour with shiny scales – he needs to look good if he wants to attract a female.
Hunchbacked
With age, the male develops a pronounced hump on his back. The hump shows who is the strongest. When it comes time to mate, the females prefer the male with the biggest hump.
