HI dangreen. I had some snails, not limpets when I added some java fern. I had 4 dwarf chain loaches, and they ate them up real quick. The chain loaches are good at it as they can easily fit between the plants, however I'm not very sure about its effectiveness at clearing limpets. But they did well at clearing pond snails for me
