Meet the Contenders: Assassin Snail vs. Malaysian Trumpet Snail
Before we deploy our cleanup crew, it’s important to understand both the problem and the solution. Knowing the nature of these two snails is the first step in our assassin snail eating malaysian trumpet snail guide.
The Unwanted Guest: The Malaysian Trumpet Snail (MTS)
Malaysian Trumpet Snails (Melanoides tuberculata) often hitchhike into our tanks on live plants or in bags of fish from the store. They are livebearers, meaning they give birth to live young, which is why their numbers can skyrocket so quickly.
In small numbers, they’re actually beneficial! They burrow through the substrate, aerating it and preventing the buildup of toxic gas pockets. The problem is, they rarely stay in small numbers. An abundance of MTS is often a sign of overfeeding, as they thrive on leftover fish food.
The Hero Arrives: The Assassin Snail (Clea helena)
Enter our hero: the Assassin Snail. With their striking yellow and dark brown striped shells, they are as beautiful as they are effective. Unlike MTS, they are not pests; they are specialized predators of other snails.
These snails are methodical hunters. They don’t just mindlessly munch on anything; they actively seek out and consume other snails. This makes them the perfect, targeted solution for an MTS outbreak. They are nature’s answer to a common aquarium imbalance.
The Hunt is On: How Assassin Snail Eating Malaysian Trumpet Snail Actually Works
So, you’ve added assassins to your tank. What happens next? The process is a fascinating display of predator-prey dynamics right in your aquarium. It’s not a frantic battle, but a slow, deliberate hunt that makes for fascinating observation.
The Stalking and Trapping Method
Assassin snails are clever hunters. They often bury themselves in the substrate with only their siphon—a small tube used for breathing—sticking out. They lie in wait for an unsuspecting MTS to crawl by.
When a target is near, the assassin snail emerges and uses its long, extendable proboscis to reach into the pest snail’s shell. It then consumes the snail from the inside out, leaving behind a clean, empty shell. It’s an incredibly efficient process and a core part of how to assassin snail eating malaysian trumpet snail populations are controlled.
Will They Eat All My MTS? The Pace of Predation

This is the sign that your assassins are hard at work. Over several weeks, you will see a significant and lasting reduction in the pest snail population.

Step 1: Assess Your Pest Snail Problem
Before you buy, take a good look at your tank. How severe is the infestation? A good rule of thumb is to start with one assassin snail for every 10-20 pest snails you can see at any given time. For a general tank size estimate:- 10-20 Gallon Tank (mild infestation): 2-3 Assassin Snails
- 30-55 Gallon Tank (moderate infestation): 5-8 Assassin Snails
- 75+ Gallon Tank (heavy infestation): 10-15 Assassin Snails
It’s always better to start with fewer and add more later if needed. They will breed, but very slowly compared to MTS.

Step 2: Acclimate Your New Assassins
Like any new addition to your aquarium, assassin snails need to be acclimated properly to avoid shock. The drip acclimation method is best, but even floating the bag in your tank for 20-30 minutes to equalize the temperature and then slowly adding small amounts of your tank water to the bag over another 30 minutes will work wonders. -
Step 3: Patience is a Virtue: Observing the Process
Once released, your assassins might bury themselves in the substrate for a day or two. Don’t worry—this is normal behavior. They are getting used to their new environment and will start hunting when they’re ready.Keep an eye out for those tell-tale empty shells. This is your visual confirmation that the natural pest control process has begun. Just sit back, relax, and let nature take its course.

Common Problems with Assassin Snail Eating Malaysian Trumpet Snail (and How to Solve Them!)
Even with a natural solution, you might run into a few questions or concerns. Don’t worry! Here are the most common issues and their simple solutions, making this a complete assassin snail eating malaysian trumpet snail care guide.
“My Assassins Aren’t Eating!”
If you don’t see empty shells right away, there are a few possible reasons. First, they might still be acclimating. Give them a few days. Second, they might be full! If there’s a lot of leftover fish food, they may opt for that easy meal first. Try slightly reducing how much you feed your fish to encourage them to hunt.
“What Do They Eat After the Pest Snails Are Gone?”
This is a fantastic question and a crucial part of responsible ownership. Once the MTS population is under control, your assassins will need a food source. They are carnivores and will readily accept protein-rich foods. You can feed them:
- Sinking carnivore pellets
- Frozen bloodworms or brine shrimp
- High-protein fish flakes
Feeding them once or twice a week is plenty to keep them healthy and prevent them from starving.
“Will They Harm My Other Snails or Shrimp?”
This is a critical point. Yes, an assassin snail will eat any other snail it can catch. Do not keep them with prized ornamental snails like Mystery Snails, Nerite Snails, or Rabbit Snails. They will hunt and eat them.
As for shrimp, the story is a bit better. Healthy adult shrimp (like Cherry Shrimp or Amano Shrimp) are far too fast and agile for an assassin snail to catch. However, a sick or dying adult shrimp, or very tiny baby shrimp (shrimplets), could potentially become a meal. In a well-planted tank with plenty of hiding spots for shrimplets, most keepers find they can coexist without any major issues.
Frequently Asked Questions About Assassin Snail Eating Malaysian Trumpet Snail
How many assassin snails do I need for a 20-gallon tank?
For a typical 20-gallon tank with a moderate MTS problem, starting with 3 to 4 assassin snails is a perfect number. This is enough to make a noticeable impact over a few weeks without being too many for the tank long-term.
Will assassin snails reproduce and take over my tank?
It’s highly unlikely. Assassin snails need both a male and a female to reproduce, and they lay single eggs one at a time. Their reproduction rate is incredibly slow compared to pest snails. You will not trade one population boom for another, which is one of the biggest benefits.
Can I keep assassin snails with my prized Mystery Snails?
Absolutely not. An assassin snail cannot tell the difference between a “pest” snail and a “pet” snail. It will hunt and eat any snail it can overpower, including your beautiful Mystery, Nerite, or Rabbit snails. Keep them in separate tanks.
How long does it take for assassin snails to clear an infestation?
Patience is key. For a moderate infestation, you should see a significant reduction in the pest snail population within 4 to 8 weeks. For a very heavy infestation, it could take a few months. Remember, it’s a slow, steady, and sustainable process.
Your Aquarium, Balanced and Beautiful
You now have all the expert knowledge you need to confidently use assassin snails to manage a Malaysian Trumpet Snail problem. You’ve learned how they hunt, how to introduce them, and how to care for them for a truly balanced and healthy aquarium.
By choosing this natural path, you’re not just solving a problem; you’re creating a more complete and fascinating ecosystem right in your home. You’re moving beyond simply keeping fish and becoming a true aquarist who understands and works with nature.
