Do cherry shrimp eat fish poop?

No, cherry shrimp do not eat fish poop. Sometimes, cherry shrimp will mistake fish poop for food, but once they realize it’s poop, they will immediately spit it back out.

This is a common misconception about cherry shrimp. Despite being bottom dwellers, cherry shrimp will only eat nutritious food sources, and fish poop is hardly nutritious.

For that reason, you can’t rely on cherry shrimp to clean your tank. No matter how many cherry shrimp you decide to keep, they won’t clear fish poop from the tank.

In addition to not consuming the poop of other fish, cherry shrimp produce their own waste as well. In order to ensure a clean, healthy tank, clean the tank and change 10-25% of the water at least once a month.
