What Do Minnows Eat In The Wild?

In the wild, minnows feed on a variety of prey, including plankton, insects, and other small aquatic creatures. They are opportunistic feeders, which means they will eat whatever is available to them at the time. Minnows are also known to feed on algae, which helps to keep the water clean and clear.


Plankton is a crucial part of a minnow’s diet and is made up of tiny organisms that float in the water. These include algae, small crustaceans, and other tiny creatures that are consumed by the minnows. Minnows have small, slender bodies that allow them to swim through the water and filter feed on the plankton.



Insects are another common food source for minnows. They feed on a variety of insects, including flies, mosquitoes, and other insects that fall into the water. Minnows have sharp eyesight, which allows them to easily spot and catch insects that are floating on the surface of the water.

Other Aquatic Creatures

In addition to plankton and insects, minnows also feed on other small aquatic creatures. These can include crustaceans, such as small shrimp and crayfish, and other small fish. Minnows are known to feed on the eggs of other fish, which helps to keep the population of other fish species in check.
