What species of clown fish are good with guppies?

It's generally not recommended to keep clownfish and guppies together. While there are some instances where it might work, there are several reasons why this is not a good combination:

* Different water parameters: Clownfish prefer brackish water with a higher salinity than guppies, which need freshwater. This makes it difficult to create an environment suitable for both species.

* Aggression: Clownfish can be aggressive towards smaller fish, especially if they feel threatened or their territory is invaded. Guppies are small and relatively peaceful, making them vulnerable targets.

* Diet: Clownfish are carnivores and require a diet of meaty foods, while guppies are omnivores and can be fed a variety of flakes, pellets, and live food. This makes it challenging to provide both species with their required nutrients.

However, there are some exceptions:

* Smaller clownfish species: Some smaller clownfish species, like the ocellaris clownfish (also known as the percula clownfish), are generally less aggressive than larger species.

* Experienced aquarist: If you're an experienced aquarist with a large, well-established tank and a good understanding of their specific needs, you might be able to successfully keep clownfish and guppies together.

Instead of keeping clownfish and guppies together, consider these alternative pairings:

* Clownfish with other reef fish: Clownfish are well-suited to reef tanks with other peaceful and compatible fish species, such as damsels, gobies, and wrasses.

* Guppies with other peaceful, small fish: Guppies thrive in community tanks with other peaceful, small fish like neon tetras, platys, and rasboras.

Remember: Always research the specific needs of the fish you're considering keeping together and choose compatible species that thrive in similar environments.
