Ive tried lettuce and a pickle, both only netted me about 5 or 6 snails. Yesterday i got fed up, and i stood at my 20 gallon tank for about an hour, just catching the snails off of the glass in a net and tossing them in a container and flushing them. I swear it had to be at least a hundred of them (no exageration), within a 24 hour period that i got rid of, and i still see some that i cant get to right now because there behind bogwood or stuck on plants but im determined to get them. Any other ideas, i dont want to use chemicals, i have a strict rule against that
