Question: what aquarium fish eat snails?
Answer: Any respectable Clown loach or Yo-Yo Loach would give their right fin for a snail dinner. They will sift through the gravel, sucking any snail they find right out of its shell. Loaches will even dive under the substrate in their snail hunting quest. Labyrinth fish, such as Bettas and Gouramis, will also eat snails.
