Aquariums: New tank and fish after 20 years

Hey, my daughter and son really love fish, so I thought it would be a good idea to get back into the hobby. I had a huge tropical tank about 20 years ago, and I loved watching the tiny angelfish and other fish grow to massive sizes over the years. It won't be the same with guppies, but they seem happy enough. The only problem I have is with the snail infestation. The real plants we bought must have harbored a few. So far, I've counted and removed six snails. (They're a different breed from the two large snails we have, and their shell shapes are different.) Do you know of an easy way to bait or capture them? The place where we bought the fish and plants advised us to remove them. They're like pests.
