Why People Choose Trapdoor Snails
In the wild these snails live in ponds and gullies. As captive pets they are suitable for the pond and aquarium. Trapdoor snails tend not to bother plants unless underfed. As omnivores they like to eat algae found growing in the water and also consume the leftover food missed by fish. This gives them the dual purpose of managing green slime and disposing of waste.
Compared to most snail species the trapdoor has few young. They are a livebearer which only gives birth to offspring in limited numbers. This can be an advantage where other snail species can quickly multipy and dominate the aquarium or pond they are kept in.
