What fish eat snails?

I have a 10 gallon tank and it holds 3 indian dwarf puffer fish/pea puffers. they love snail cuz they are small enough to suck out the snails. if you have a snail problem i would remove the fish from your tank and put a snail killing chemical in. i have also heard of snail traps you can put in your tank and not have to remove your fish. i would at fast because snails multiply VERY FAST, or you can smash them with your fingers. Also there are such things as ASSASSIN snails that will eat brown snails.
