Are koi compatible with shrimp and snails?

Koi can be kept with shrimp and snails, but caution is advised. Koi are known to eat small creatures, including shrimp, especially if they are small enough to fit in their mouths. Larger snails may be safe, but koi might still disturb them. To ensure compatibility, provide ample hiding spots for shrimp and consider the size of the species involved.
