Can Guppies and Cory Catfish Live Together?

Yes, guppies and cory catfish can live together in the same tank. They are both peaceful species that generally do not bother each other. Guppies are active swimmers that prefer the middle and top of the tank, while cory catfish stay near the bottom, scavenging for food. This difference in activity zones reduces conflicts and ensures a balanced ecosystem.

However, ensuring compatibility depends on several factors, such as tank size, water parameters, and feeding routines. These two species can thrive together in harmony with proper care and planning.

Benefits of Keeping Guppies and Cory Catfish

Keeping guppies and cory catfish together offers several advantages:

  • Balanced Tank Ecosystem: Cory catfish are natural cleaners that eat leftover food and algae, reducing waste.
  • Aesthetic Appeal: Guppies add vibrant colors, while cory catfish bring variety with their unique patterns.
  • Peaceful Coexistence: Both species have calm temperaments, making them ideal for community tanks.
