I want to get rid of all the snails I have, the name of these snails are the "Ramshorn snail" (Planorbis corneus), I don 't want to treat my ta nk with chemicals as i've heard that it can effect my fishes, I tried hand picking them out, but it's getting a bit silly now as there are too many.

My question is that is there any other type of snails or anything else that will eliminate these smaller snails?

Snails don't eat snails so that option is out. If you have that many snails then you are over feeding your tank. Snails multiply according to the food available. Try cutting your feedings down and do a couple of extra water changes. they will continue to appear until all the eggs are hatched. Just keep on doing the extra water changes and feed a little less.

You could catch them and send them all to me.
