Assassin Snail

Assassin Snail key facts

Care level

Beginner-friendly

Lifespan

5-10 years

Size

Shell height 18-32mm

Diet

Other snails, worms, frozen foods and sinking prepared foods

Tank

Use a fine sand it can burrow into; coarse gravel prevents burrowing and its natural behaviour. No special filtration or equipment is needed, but it will starve once the supply of prey snails runs out, so plan its feeding.

Water Temperature & Quality

No verifiable pH, hardness or temperature figures exist for this species, so none are given. It is a tropical Southeast Asian snail, and the basic requirement is to avoid strongly acidic water, which erodes the shell.

Tank Mates

It preys on other snails, so do not keep it with snails you want to keep. It does not attack fish, though slow-moving small bottom crustaceans can be taken. It is most often introduced to control a snail outbreak.

Diet & Feeding

Carnivorous, feeding on other snails and worms. Once the prey snails are gone, offer frozen bloodworm or a sinking carnivore food. It does not eat algae, so it is no use as an algae grazer.

Breeding & Spawning

The sexes are separate rather than hermaphroditic, and the English Wikipedia states that it is not currently known how to tell male from female. The manner of egg laying is not described here, as the sources used for this entry do not cover it.

Health & Notes

Where introduced it can seriously threaten native freshwater gastropods, so never release it into outdoor waters. If you add it to clear a snail problem, decide in advance what to do with it once the prey is gone. It is not listed by CITES.

About Assassin Snail

Assassin Snail is a carnivorous freshwater snail with a bee-like striped shell that preys on other snails. It hides in the substrate and is easy to keep, making it a popular pick for controlling unwanted snail populations.

7 things to know before welcoming a Assassin Snail

1. 1A Carnivorous Snail

   Assassin Snails are carnivorous and prey mainly on other snails. They eat little to no plant matter, so their diet should center on live snails or foods made for carnivorous snails.

2. 2Burrows in the Substrate

   These snails spend most of their time buried in the substrate, only emerging when they sense food nearby. Give them a substrate deep enough to burrow into comfortably.

3. 3Bee-Like Striped Shell

   Their cone-shaped shells feature alternating bands of dark brown and pale tan, a pattern often likened to a bee's coloring.

4. 4Gentle with Tankmates

   Assassin Snails are peaceful and won't harm fish or shrimp. They're often added to community tanks specifically to help manage unwanted snail populations.

5. 5Shell Height: 18–32mm

   Adults typically reach a shell height of about 18 to 32mm. They grow at an unhurried pace, so their development is easy to observe over time.

6. 6Watch Their Numbers

   Because their numbers depend on the supply of other snails to prey on, they tend to increase at a modest pace when food is limited. Keep an eye on tank conditions and adjust numbers as needed.

7. 7Beginner-Friendly

   Assassin Snails are considered easy to keep and don't require special equipment. They're a great starting point for anyone new to snail keeping.

Frequently asked questions about Assassin Snail

Q.Will Assassin Snails harm other tankmates?

A.They're peaceful and won't harm fish, shrimp, or other tankmates — their prey is limited to other snails. This makes them easy to add to a community tank.

Q.Can they help control an overpopulation of pest snails?

A.Yes, they're commonly introduced to help manage overpopulated pest snails since they prey on other snail species. That said, they may not eliminate every last one.

Q.What does an Assassin Snail look like?

A.Its cone-shaped shell has alternating bands of dark brown and pale tan, a pattern often compared to a bee's coloring. Since it usually stays buried in the substrate, you won't see it out and about very often.

Q.Is this species suitable for beginners?

A.Yes, it's considered a beginner-friendly species that doesn't require special equipment. It's a good choice even if you've never kept snails before.

Q.Where do Assassin Snails usually stay in the tank?
