Being a tasty snack, rainbow runners are mainly preyed upon
by larger animals such as dolphins, dogtooth tuna and gulls,
they stay near the top of the water which makes it easier for
its predators to feed. Rainbow runners are not targeted in
commercial fishing by are hardly hit when it comes to bi-catch.

These creatures are very carnivorous and their diet
Rainbow runners main diet includes crabs, shrimp, small fish,
cephalopods and plankton. Although they have a flexible diet

Rainbow runners reach breeding maturity at the size of 60-65,
which is when they wait until the water is 27 degrees and all
the females lay hundreds and thousands of eggs. These eggs
float on top of the water creating a mat figure to keep the eggs
more protected against hungry creatures on the prowl for a
meal, but sadly only 35% of these eggs survive to a breeding
maturity.

With their shining colour they are put apart from other fish as
they are a sleek tainted grey at the top which quickly changes
\ into a pattern of blue yellow blue stripes then fades to a
casual grey. They have very small eyes limiting their sight.
Having two dorsal fins they quickly fly through the water
helping them escape predators.

In conclusion, these are not just pretty fish they are
magnificent beings that weave their way through population
downfall and still have a large number left in the world.
