Overview

Assassin Snails — Nature's Pest Snail Control

Assassin Snails (Clea helena) are the natural, chemical-free solution to pest snail infestations. With their striking yellow-and-brown striped shells, they actively hunt and consume bladder snails, ramshorn snails, Malaysian trumpet snails, and other small pest species — restoring balance to overrun aquariums. Once pest populations are under control, they switch to scavenging leftover food and detritus, never harming live plants or your fish.

Care Guide

  • Tank size: 10 gallons or larger; group of 3–6 for effective pest control
  • Water parameters: Temp 75–80°F, pH 7.0–8.0, GH 8–18 (hard water supports shell health)
  • Diet: Carnivore — pest snails are their preferred food. Once pests are gone, supplement with sinking pellets, bloodworms, and high-protein foods
  • Tankmates: Safe with most community fish and live plants. Not safe with shrimp fry or other ornamental snails (mystery, nerite, ramshorn) — they will hunt them too

Why Choose Our Assassin Snails

  • Active hunters — ready to clear out pest snail populations
  • Live arrival guarantee with fast US shipping
  • Heat or cold packs included as needed

Tank setup

  1. Use a fully cycled aquarium before adding live animals.
  2. Match tank size, flow, and hiding spaces to the species.
  3. Temperature acclimation should be gradual after delivery or pickup.
  4. Avoid sharp decor that can damage fins or sensitive bodies.

Water parameters

  1. Keep ammonia and nitrite at 0 ppm before adding livestock.
  2. Maintain stable temperature and pH instead of chasing exact numbers.
  3. Perform regular water changes based on stocking level.

Feeding

  1. Feed a varied, species-appropriate diet and remove uneaten food promptly.
  2. Avoid overfeeding during the first day after arrival.

Compatibility

Review the product facts and current tank setup before introducing new livestock.

When Live Arrival Guarantee does not apply

  1. Carrier delays
