I have same problem and just bought some clown loaches. The first ones only ate food and I returned them after squashing snails to get them a taste and still no luck. Another lfs had them in a tank with plants and they took to the snails immediately (not sure this is a good sign to get any plants there in the future! )
In just a couple of days, the snail population is noticeably smaller. I even saw one of the clowns poking at one off the glass. They do get quite big, but are very slow growers. When they get too big, I'll probably trade them in given I don't fall in love with them by then. They are fun to watch their antics in the tank.
