Are small koi carp safe in a pond with common carp and big goldfish?

Small koi carp can generally coexist with common carp and larger goldfish in a pond, but there are risks involved. Larger fish may see smaller koi as potential prey, especially if they feel threatened or are competing for food. To ensure their safety, it's important to provide ample hiding spaces and monitor their interactions closely. Additionally, maintaining a balanced ecosystem with proper filtration and water quality is crucial for the health of all fish.
