Now in answering the question on fish that eat guppies, there are two approaches we can take.

The first is where we focus on freshwater fish that eat guppies first. Then we focus on saltwater fish that eat guppies.

The other approach is where we focus on aquarium fish that eat guppies first. Then we turn to fish that eat guppies in the wild thereafter.

We will go with the second approach.

Therefore let’s start with aquarium fish that eat guppies. And this is where we find that the aquarium fish that eat (adult) guppies include leopard bush fish, clown knife fishes and Oscars. Larger angelfish are also known to eat guppies.

As for aquarium fish that eat guppy fry, the list is longer. It starts with the guppies themselves: as adult guppies are known to eat their very own fry. The list then includes bettas, pufferfish, gouramis and swordfish.

In the wild, cichlids are guppies’ key archenemies. But we also have the likes of red tiger sharks and the blue acaras among those that commonly eat guppies.

Then again, these lists are by no means exhaustive. For instance, if you were to ask, do archer fish eat guppies, the answer would be in the affirmative.

Similarly, if you were to ask, will rainbow fish eat guppy fry, the answer would still be in the affirmative.

Therefore the best thing to assert is that any carnivorous or omnivorous fish with a mouth big enough to ingest a guppy is a potential predator.

 

Which Fish Eat Adult Guppies?

An example of a fish that is known to eat adult guppies (in the aquarium setting) is the leopard bush fish.

Another example is that of Oscar fish.

What Fish Will Eat Baby Guppies?

The best fish for eating guppy babies include bettas, gouramis, swordfish and pufferfish. Adult guppies themselves are also prolific eaters of their own fry.

Therefore those are the best predator to eat baby guppies.

They can be useful to you if, for instance, there has been overbreeding in your aquarium – leaving you wondering, what do I do with all these guppies?

In other words, if you are wondering, how do you get rid of unwanted guppies, these natural predators can be very useful to you. They are some of the best fish to control guppy fry.

But we do have to mention that the fish we are making reference to here are only those that commonly pursue and eat guppy fry. But the list is not exhaustive.

For instance, if you were to ask, will angel fish eat baby guppies, the answer would still be ‘yes’. So that is similar to how posing the will betta fish eat guppy fry question yields an affirmative answer.

Frankly, pretty much any fish that eats other fish is a potential predator for baby guppies. They are small enough to fit into almost any fish’ mouth. And they are colorful enough to be easily spotted by almost any fish that is in search of food.

It is just that for some of the biggest fish, these baby guppies are too small to be worth pursuing.
