Rams horns are nice snails and can come in amazing colors like red and white and leopard! Over feeding is the primary reason there are explosions of snails. Don't forget to clean the substrate. Most people over feed. I would say cut the quantity of food in half.
If you feed 2x per day still feed 2x p/d but only half the quantity, clean the substrate well for a few weeks on the weekly pwc's and see how the snail population looks. You may need to cut back food even more. Some people give their fish a fast day/no food to make sure they clean up the aquarium.
People with Puffer fish and Loaches will take them off of your hands too!
