Trapdoor Snails
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. Unlike other snails, they don’t reproduce rapidly, so you won’t have to worry about overpopulation.
Perfect for koi ponds, wildlife ponds, and ornamental water gardens, Trapdoor Snails are peaceful, attractive, and an excellent long-term addition to your aquatic ecosystem.

Location – Trapdoor snails eat algae on the bottom of the pond
Non-invasive – Slow reproduction prevents overpopulation
