"Introducing the Assassin Snail for aquariums! A natural solution for controlling pest snails while adding intrigue to your tank."

Detailed Description:


  • The Assassin Snail (Clea helena) is a fascinating freshwater snail prized by aquarists for its ability to control pest snail populations.
  • Originating from Southeast Asia, these snails are renowned for their striking appearance and efficient predatory behavior.


  • Assassin Snails feature a cone-shaped shell with yellow and brown bands spiraling around it, resembling a miniature version of a marine cone snail.
  • Their elongated body is adorned with sensory tentacles and a siphon used for detecting prey and navigating their environment.
  • Adult Assassin Snails typically reach a size of 1 to 2 inches, making them suitable for aquariums of various sizes.

Water Conditions:

  • Optimal water temperature: 72-78°F (22-26°C).
  • pH range: 7.0-8.0.
  • Water hardness: 5-15 dGH.
  • Maintain stable water parameters to ensure the health and well-being of Assassin Snails.
  • Provide adequate filtration and regular water changes to keep water quality high.

Tank Setup:

  • Assassin Snails thrive in well-established aquariums with ample hiding places and substrate for burrowing.
  • A tank size of at least 10 gallons is recommended for a small group of Assassin Snails.
  • Incorporate live plants such as Java Moss, Anubias, and Vallisneria to provide cover and create a natural environment.
  • Ensure the tank has a secure lid as Assassin Snails may climb out of the water.

Tank Mates:

  • Assassin Snails are generally peaceful and can coexist with a variety of tank mates, including peaceful fish, shrimp, and other snail species.
  • Compatible tank mates include Tetras, Rasboras, Corydoras Catfish, Dwarf Cichlids, and peaceful freshwater shrimp species.
  • Avoid keeping them with aggressive or predatory species that may harass or prey on the Assassin Snails.

Feeding Habit:

  • As carnivorous predators, Assassin Snails primarily feed on other snails, including pest species such as Malaysian Trumpet Snails and Ramshorn Snails.
  • They use their proboscis to pierce the shells of their prey and consume them from the inside out.
  • If pest snails are not available, Assassin Snails can be supplemented with sinking pellets, algae wafers, and small meaty foods such as bloodworms or brine shrimp.
  • Feed Assassin Snails sparingly, as they have a slow metabolism and may not require frequent feedings.

Care and Maintenance:

  • Maintain a clean aquarium environment by removing uneaten food, debris, and excess waste.
  • Perform regular water changes of 25% every two weeks to prevent the accumulation of toxins and maintain water quality.
  • Monitor Assassin Snails for signs of illness or stress, such as reduced activity, shell damage, or abnormal behavior, and address any issues promptly.
  • Provide calcium supplements such as cuttlebone or calcium-rich foods to support shell growth and maintenance.


  • Assassin Snails are gonochoristic, meaning they have separate sexes, with males and females needed for reproduction.
  • Breeding may occur in aquariums with suitable conditions, but it is less common compared to their predatory behavior.
  • Females typically lay small, jelly-like egg masses on hard surfaces such as rocks or aquarium glass.
  • After a gestation period of several weeks, juvenile Assassin Snails hatch from the eggs and resemble miniature adults.
