Type: Ramshorn Snail Benefits of this type: It eats algae that grow on glass and plants, eats dead fish and plants, and eats plant leaves that are weak and about to die. And the snail reproduces quickly and has beautiful and stunning colors, unlike other types, and its size reaches the size of a thumb. The colors I have are the same as in the pictures, and the sizes are small and medium. Price: 10 snails for 15 riyals for adults, and 6 snails for 10 riyals for small ones. Note: The snail does not eat hair algae or black beard algae. It eats easy and light algae. Delivery is available to nearby neighborhoods for a symbolic price.
