Can Koi have snails or other live foods to eat?

Koi eat snails and tiny crustaceans in the mud as part of their natural biology. Snails living in temperate climates don't carry diseases for fish, however in
equatorial countries the snails can carry digenetic trematodes and worse.

Snails don't hurt the koi's mouth (neither their sucker or their crushing teeth) - they are biologically adapted to consuming the escargot and most other fibrous or shelled critters they can forage from the muddy bottoms of their natural surroundings. You may hear a lot of hysterical whining about feeding blood worms to Koi and Goldfish. Some pundits fail to realize that the "whirling disease" these worms may carry is infectious ONLY to salmonid fishes, not Koi and Goldfish. Other live foods include earth worms, and silkworm pupae. You can feed these "straight up" or you may decide to soak them first.
