Whether guppies will eat shrimp mainly depends on the shrimp's body size and the breeding environment. The specific situations can be divided into the following:

I. Analysis of Feeding Behavior
- High Risk for Young Shrimp
Guppies will actively prey on young shrimp that are only a few millimeters in body length (such as newly hatched cherry shrimp or baby black shell shrimp). Due to their omnivorous nature, they regard tiny shrimp as natural food.
- Safer for Adult Shrimp
Adult utility shrimp (such as black shell shrimp measuring 2-4 centimeters) are usually not swallowed because their body size far exceeds the size of a guppy's mouthparts.
II. Mixed Breeding Management Recommendations
- Environmental Optimization
Setting up dense shelters in a planted tank (such as moss plants or shrimp houses) can increase the survival rate of young shrimp.
- Feeding Strategies
Providing high-protein live food (such as hatched brine shrimp or frozen bloodworm larvae) can reduce the motivation of guppies to hunt shrimp fry.
III. Precautions
If it is necessary to protect the shrimp breeding group, it is recommended to separately raise young shrimp or choose to mix adult shrimp of larger sizes. The key to whether guppies and shrimp can coexist lies in the shrimp's growth stage and the ecological balance in the tank.
