Will angle fishes eat a guppies when they are together?

It's highly likely that an angelfish will eat a guppy if they are kept together. Here's why:

* Natural Diet: Angelfish are carnivores and their natural diet consists of insects, smaller fish, and crustaceans. Guppies are a suitable size and species for them to prey on.

* Aggression: While angelfish are generally peaceful, they can be territorial and aggressive, especially towards smaller fish. This is particularly true if the angelfish feels threatened or stressed.

* Guppy Size: Guppies are relatively small and vulnerable compared to the size of an angelfish. They are easy targets for an aggressive angelfish.

However, there are factors that can influence the situation:

* Tank Size: A larger tank provides more space for the guppies to hide and avoid the angelfish.

* Tank Mates: Adding more peaceful tank mates can distract the angelfish from the guppies.

* Angelfish Temperament: Some angelfish are more peaceful than others. You can observe their behavior before introducing them to the guppies.

In general, it's best to avoid keeping angelfish and guppies together in the same tank. The risk of the angelfish eating the guppies is high, and it's not a suitable combination for a peaceful community tank.

If you are determined to keep them together:

* Choose a large tank with plenty of hiding places for the guppies.

* Carefully observe the angelfish's behavior and remove any guppies if they become targets.

* Consider using a divider or separate tank if necessary.

It's always best to research the compatibility of fish species before introducing them to your aquarium to ensure the safety and well-being of all your aquatic companions.
