Trapdoor snails - Viviparus viviparus Keep your pond clear and healthy with Trapdoor Snails – one of the best choices for natural pond maintenance. These robust freshwater snails are well-suited to outdoor UK ponds thanks to their hardy nature and unique “trapdoor” operculum, which protects them from predators and cold temperatures. Trapdoor Snails feed on algae, decaying vegetation, and uneaten fish food, making them a key part of your pond’s clean-up crew.
