What do fish eat?

Fishes in general are not fussy about food. They have a very diverse diet chart which has a lot of shift and change. They adapt their food habit to the surrounding. Different types of fish have different choices of food. And a lot of it depends on where the fishes dwell.


Saltwater fish or ocean fish have the most diverse diet chart. They do not have any specific hate for any type of food. Some they prefer more than the other that is all.


The fish of the ocean will eat red, green or any type of algae. They do not differentiate between microalgae or macro algae either.

Carnivore’s fish:

If the fish is carnivores they will opt for shrimp or any other small fish instead of algae.


No matter the type of fish, the plankton is a constant for ocean fish.


Pond water fish or freshwater fish will gobble on anything you give them. Usually, the fish are habituated so it is not a bother for you.

Natural food:

Weeds, algae and other insects in the pond are good for the pond fishes. They will also eat the plankton they find around them. Some will even chow down on tadpoles even.


Apart from what they find in the nature, the fishes also need nutrition from outside. Which is why the pond fishes are sometimes given supplements like different vitamins or zinc. Some even give them bread.


If you have fish in your home, meaning aquarium, they will need a specific diet chart consisting of a mix of all kinds of vitamins and food.

There are specific food for aquarium fishes which have a little bit of everything. They are constantly fed to them.

Plant and meat:

Any plants found in the aquarium is good. So are planktons and meat like frozen shrimp.

Can fish feed on frogs?

It is not an entirely uncommon scenario where a fish eats a frog. Some fishes have predatory instincts, and these instincts kick in when they see or come near a small sized frog. That is when they will fight and eventually eat up the frog. This is actually very common in nature.

Fishes eating tadpoles is not hard to believe but a fish eating up a whole frog is not something anyone would believe without proof.

If a frog is smaller than the fish, there is a good chance of it being eaten by that fish. Tadpoles or the grown-up frog both are the same to some fishes if they are larger in size than the frog.

There are some fishes who particularly like eating frogs. Fishes who have a dominant predatory instinct like the Northern Pike or the Catfish tend to have a liking for the frogs as food.

Final thoughts

Fishes being very easy going with their food habit will eat frog food as well. They do not fuss over any type of food in fact. If the frog food is small enough for them to have they will eat it. Sometimes the frog food will get soggy, making it easier for the fishes to gobble up on the food.
