OMG I hate Snails!!! I've tried feeding less and it doesn't matter in my tank. They don't clean my tank for crap, just hang on filters and heaters. I watch each piece of food get eaten and they are still there. I personally feel that once you have snails, you can't get rid of them entirely. Clown loaches MAY eat them but they get real big too. Yoyo loaches are better, but will they actually eat snails, it depends on the tank and the fish. I'd try the veggy trick or just keep taking them out to keep them under control. Assassin snails do work but I heard they will only eat snails of similar size which is pointless when you have 20 monsters stuck to the glass. I hate snails, I hate snails, I hate snails.
