Cincinnati Zoo’s Animal Excellence Scientists Study Blue Tilapia in Hippo Cove

Hippo Cove is not just home to Fiona and her family, but to 300 blue tilapia neighbors as well. The blue tilapia play an important role in helping to keep their shared habitat clean by eating the hippo’s dung and dead skin. It is a great example of a symbiotic relationship!

Right now, the Animal Excellence Science Team at the Cincinnati Zoo & Botanical Garden are “o-fish-ally” studying the blue tilapia in Hippo Cove to learn more about their activity and space use. We are observing their behavior to understand how they use their habitat and how much time they spend with each other. We are also working with our Water Quality Team to get live temperature updates that we incorporate into our study. Studying how the blue tilapia interact with their environment, from their hippo neighbors to the water quality itself, we can make informed decisions to support their husbandry and ensure they have the best possible conditions to thrive.

This project reflects Cincinnati Zoo’s commitment to animal excellence for all species. Whether big or small, furry or finned, our Animal Excellence Science Team focuses on the wellbeing of all the species that call the Zoo home. Every animal matters, and our research helps us provide the best care possible.

As we learn more about the blue tilapia in Hippo Cove, we will continue making changes in their husbandry and share updates on their behavior. Stay tuned for more insights into how Cincinnati Zoo and the Animal Excellence Science department are leading the way in animal wellbeing for all species!
