Fascinating to watch
Assassin Snails (Anentome helena) are predatory freshwater snails used to reduce pest-snail populations without chemical treatments.
They should not be treated as community cleanup snails because they may attack ornamental snails and vulnerable invertebrates.
Care Notes
Assassin Snails are predators. Use them only where you want pest-snail control and keep them away from ornamental snails you want to protect.
Supplement with meaty foods after pest snail numbers decline.
Ornamental snails (Mystery, Nerite, Rabbit, smaller Assassins) — will be predated
Shrimp-breeding tanks — Assassin Snails may eat molting shrimp and shrimplets
Delicate small invertebrates and dwarf shrimp colonies you want to expand
Pufferfish and large loaches — will predate Assassin Snails
Crayfish — will attack snails
Expert Advice
Razz Aquatics Recommendation
Use Assassin Snails only when you actually want predation on pest snails. Keep them out of tanks containing ornamental snails you want to protect or active shrimp-breeding colonies. Once pest snails are reduced, provide meaty sinking foods.

Common Questions
Assassin Snail FAQ
Are Assassin Snails safe with shrimp?+
Not for shrimp-breeding tanks. Adult shrimp are often too mobile to be easy prey, but shrimplets and freshly molted shrimp can be vulnerable.
What happens when the pest snails are gone?+
Feed meaty sinking foods or frozen foods so the Assassin Snails still receive an appropriate diet.
How are Assassin Snails shipped?+
Snails ship Monday through Wednesday in insulated packaging with weather-appropriate protection and typically arrive within the selected delivery window.
Will Assassin Snails eat Mystery, Nerite, or Rabbit Snails?+
They can attack other snails, so do not keep them with ornamental snails you want to protect.
Will Assassin Snails eat algae?+
No. They are predators and scavengers rather than algae grazers.
Is there a live arrival guarantee?+
Yes. Every order is covered by our Live Arrival Guarantee. Photograph any DOA in the sealed bag on delivery day and submit a claim through the Start a Claim page.
